As the mining industry tightens its belt due to costs exceeding cooling prices for many operations, the cost cutting machine has kicked in yet again. Having been through this same cycle a few times and seen the transitions from the overspending to the cost cutting phase of the cycle, we have noticed several traps that mining operations can get caught by. TSV Mining has often witnessed that not all cost cutting methods transfer well from site to site, and some may have hidden traps that become detrimental to the longer term sustainability of a mine.
LESS CRISIS, MORE PROJECTS: TRENDS IN SHUTDOWN & TURNAROUND MANAGEMENTMateus Siwek
The article discusses trends in shutdown and turnaround management. It notes that changing market conditions and increased competition have led plant operators to optimize shutdown planning to reduce downtime and increase efficiency. This has made turnaround scheduling more complex as operators seek to integrate more investment projects into shutdowns. The challenges of maintaining flexibility in scheduling while increasing project integration are discussed. Interviews provide perspectives from contractors on advantages and challenges of project integration during shutdowns, as well as trends in investment projects and the future of plants in Europe.
The document discusses estimating the value of conducting Highly Accelerated Life Testing (HALT) on new product prototypes. It uses the example of a new game controller design project to estimate costs and potential benefits. Conducting HALT on initial prototypes for the controller could cost $24k but uncover design weaknesses, allowing issues to be fixed before manufacturing starts and avoiding an estimated $15 million in lost sales from delays. The return on investment of HALT for this project is calculated to be over 60, indicating it is worthwhile to conduct the testing.
In this paper we will look at the cost impact of delay without a change in project scope
or project rework. This condition is most closely associated with general delay as a
result of:
Extended decision making time frames by the project owner
Project wide stop work orders from any of a variety of causes.
No loss of productivity from project disruption has been reflected except in the case
considered at the end of this paper (Figure 13) where lost productivity from retrograde
behavior of the site labor’s learning curve or production curve is specifically considered.
This differs from the so called “measured mile” approach often used in calculating
disruption impacts.
In actual project situations the cause of delay is often associated with changed scope
or rework and disruption and concomitant loss of productivity are real factors. The
simplified analysis presented here is intended to influence project decision making
processes by better dimensioning the cost of delay in establishing evaluation and
decision making time frames. The cost of a lack of timely decision making is seldom
reflected in project governance processes.
Reducing Product Development Risk with Reliability Engineering MethodsWilde Analysis Ltd.
Overview of how reliability engineering methodology and software tools can help companies manage risk during product development and improve performance.
Presented at the Interplas'2011 exhibition and conference at the NEC on 27th October 2011 by Mike McCarthy.
This presentation looks at how ‘Reliability Engineering’ tools and methods are used to reduce risk in a typical product development lifecycle involving both plastic and metallic components. These tools range in complexity from simple approaches to managing product reliability data to the application of sophisticated simulation methods on large systems with complex duty cycles. Three examples are:
- Failure Mode Effects (and Criticality) Analysis (FMECA) to identify, manage and reuse information on what could go wrong with a design or manufacturing process and how to avoid it
- Design of Experiments for optimising performance through a structured and efficient study of parameters that affect the product or manufacturing process (e.g. injection moulding)
- Accelerated Life Testing to identify potential long term failure modes of products released to market within a shortened development time.
We will explore how gathering enough of the right kind of data and applying it in an intelligent way can reduce risk, not only in plastic product design and manufacture, but also in managing the associated supply chain and in the ‘Whole Life Management’ of products (including warranties). Furthermore, we will show how ‘sparse’ data gathered from previous or similar products, such as field/warranty reports, engineering testing data and supplier data sheets, as well as FEA, CFD and injection moulding/extrusion simulation, can inform and positively influence new product design processes from concept stage onwards.
When a failure happens, you want to find out why and take action to prevent future occurrence. To do this you must capture as much evidence - verbal, physics, digital - as possible. This presentation discusses that.

TSV Mining: Variation Analysis in Mining Part 1 - Precision and AccuracyTotius Mining
Variation is one of the largest value destroyers in the mining industry. This presentation shows how to reduce and manage variation using the definitions of Precision and Accuracy.
The ability to remove floating bottlenecks in an operation is linked to the precision of processes, and to the demand placed on them. Often in mining, the cost associated with removing processes from being an occasional bottleneck is higher than the gain in throughput.
Process capacity and inventory requirements are heavily linked to precision, which is rarely reviewed by any mining operations.

TSV Mining: Critical density in mining and changes to sustainable low cost pr...Totius Mining
This document discusses the concept of critical density as it relates to open cut mining systems. It draws an analogy between traffic flow modeling and mining processes, noting that as density increases, a system will pass a critical point and become metastable and potentially unstable. It describes how applying the principles of critical density and understanding where a mining operation sits in relation to this point can help identify strategies to improve throughput and productivity in a sustainable way, such as increasing operational scale, improving material flow, or enabling parallel processing. Maintaining awareness of an operation's critical density point over time is important for managing the impacts of changes to the system.
This document discusses green technology and its importance.

This document describes a technique for Sinhala handwritten character recognition using feature extraction and an artificial neural network. The methodology includes preprocessing, segmentation, feature extraction based on character geometry, and classification using an ANN. Features like starters, intersections, and zoning are extracted from segmented characters. The ANN was trained on these feature vectors and tested on 170 characters, achieving an accuracy of 82.1%. While the technique showed some success, the author notes room for improvement, such as making the system more font-independent and improving feature extraction and character separation.
Scaling up industrial microbial processes is a complex endeavor that requires careful planning and execution to be successful. It involves increasing laboratory-scale processes to full commercial production levels over many years and at a high financial cost. If not approached properly, scale-up can lead to underperformance, delays, and project failure. To scale up successfully, one must begin with a clear vision of the final commercial process, be diligent in considering all critical details, and prepare for unexpected challenges that may arise.
Gaining control of maintenance costs through effective tools and continuous process improvement requires aligning analytics, budgeting, scheduling, warranty, and mobility solutions. This allows visibility into costs and helps prioritize critical assets to focus spending. Analytics provide insights to optimize maintenance programs and budgets. Budgeting tools like zero-based budgets and revisions help manage costs. Effective planning and scheduling, such as focusing on critical equipment, can increase uptime and revenue while decreasing costs. Warranty management and mobility solutions can further reduce spending and increase efficiency.

- The document discusses issues with current commercial practices in process control engineering and lack of agreement on how to measure the value and performance of control systems.
- It argues that the primary purpose of process control should be to maximize expected net present value profit (ENPVP) and that Clifftent, a quantitative risk management method, provides a rigorous way to measure the financial value of dynamic performance and improved control.
- Using Clifftent, the value of process control comes from three sources: optimizing setpoints, reducing dynamic variance at a setpoint, and further optimizing setpoints for the reduced-variance situation, taking into account penalties for violating process limits.
Impact of Planning Decision Support Tools on Mining Operations ProfitabilitySchneider Electric
Changes in the mining industry business environment are leading to gradual changes in how the supply chain (from ore extraction at the mine to delivery at customer sites) is managed. Global demand is flattening and available supply is increasing. This means that complex planning business models that were developed in an era of supply “push” need to be altered to accommodate a market reality of demand driven “pull”. This white paper introduces a decision support methodology that results in reduced cost, improved throughput, enhanced quality, and increased profit.
Sliding Oil Prices: Predicament or ProspectCognizant
Sliding oil prices have led to cost-cutting across the oil and gas industry. Upstream companies are reducing operational costs through layoffs and postponing capital spending. However, the document recommends that companies revisit their "value tree" to identify non-essential processes and projects to optimize, prioritizing safety and regulatory compliance. Specific strategies discussed include optimizing maintenance costs, prioritizing quick IT wins, outsourcing non-critical business processes to the cloud, and using analytics to improve asset performance and reduce non-production time.

Capacity planning involves both long-term and short-term considerations. Long-term capacity planning relates to strategic issues like facility locations and technology. Short-term capacity planning concerns scheduling, labor shifts, and balancing resource capacities to efficiently handle unexpected demand changes. Critical capacity decisions involve determining optimal levels of raw materials, equipment, labor, storage and integrating these factors based on demand forecasts. Capacity is impacted by various interrelated factors and effective planning is needed to meet requirements at minimal cost while maintaining quality and competitiveness.
Managing Assets for Maximum Performance and ValueEMC
This Ovum paper explains the importance of managing physical assets throughout its lifecycle, describes benefits seen by companies adopting asset lifecycle information management (ALIM), and provides recommendations to achieve optimal results.
The document discusses how defining asset criticality can improve business performance beyond just maintenance planning. It provides examples of how categorizing assets by importance allows a company to prioritize critical assets, improve reliability, and drive operational stability and predictability. This in turn can increase profits by minimizing downtime and disruptions on critical equipment. The document argues that asset criticality should be leveraged throughout an organization's processes to achieve greater business results.
This article discusses the benefits of implementing Total Productive Maintenance (TPM) in manufacturing. TPM involves regularly checking and maintaining equipment to maximize its lifespan and productivity. While seen as difficult to implement, TPM can reduce costs from avoided downtime and increased output. It also improves sustainability by extending the useful life of machines, reducing waste, and lowering energy usage. The article argues that ignoring TPM is unwise from an economic, environmental, and social perspective, and that adopting preventative maintenance can give companies a competitive advantage through improved efficiency and reduced environmental impact.
1. The document provides 10 strategic actions that major energy companies can take to navigate low oil prices and emerge stronger from the downturn. These include reducing above-field costs, improving asset utilization, prioritizing maintenance, resetting supplier partnerships, and equipping fields with digital technology.
2. It recommends that companies reassess capital projects, get smarter about workforce management including contractors, shrink their corporate centers, and better communicate their value stories to investors.
3. Taking decisive action through focused investments and planning ahead with a multi-year horizon will help companies position themselves for high performance, according to the document.
The document discusses reliability in asset management and maintenance. It defines reliability as machines producing quality output at design capacity for their lifetime. It discusses moving from reactive to proactive maintenance through a culture change. Key aspects are implementing preventive, predictive, and proactive maintenance approaches and using metrics to measure inputs and outputs. Case studies demonstrate benefits of condition monitoring to avoid breakdowns.
This document discusses the top 5 benefits of incorporating sustainability initiatives into factory manufacturing processes. It summarizes that sustainability offers both short-term and long-term cost savings beyond just compliance. The top 5 benefits discussed are: 1) Capital optimization through improving equipment efficiency and utilization; 2) Reducing paper usage to save costs, space, and improve collaboration; 3) Improved scalability by optimizing production and adding capacity efficiently; 4) Energy savings through monitoring usage and improving processes; and 5) Waste reduction to save on disposal costs and utilize raw materials more efficiently. The document provides examples of how practices like total productive maintenance and sustainable production can help achieve these benefits.

Europec 2016 - Chris Hopper - SPE 180176-MSChris Hopper
This document discusses project management approaches for oil and gas developments in an environment of sustained low oil prices. It notes that traditional linear project management systems have failed to deliver projects on time and budget over 70% of the time. These traditional approaches are not well-suited for complex projects with significant uncertainty. The document describes an alternative approach used in the 1990s that embraced uncertainty and allowed projects to accommodate change. It also discusses a recent North Sea project where the development plan was designed to accommodate a range of potential outcomes in order to gain project approval despite uncertainty. The document argues the industry needs approaches that produce resilient projects able to adapt to changing conditions rather than arbitrary cost cuts alone.
1. The authors analyze the limits of pursuing a strict cost-minimization strategy via experience and learning curves. While such strategies can significantly reduce costs, they can also reduce flexibility, innovation, and the ability to change strategies.
2. The article uses Ford Motor Company's experience with the Model T as a case study. Ford was highly successful at reducing Model T costs, but in the process specialized its workforce and processes such that transitioning to a new model (the Model A) was very difficult and costly.
3. More broadly, the authors conclude that intensely pursuing cost reductions can undermine an organization's innovative capabilities and flexibility to respond to competitors, limiting the benefits of experience and learning curves. Management must consider these
Testing in Financial Services - Leveraging Process MapsITC Infotech
This document discusses leveraging process maps for more efficient testing in the financial services industry. It notes that traditional testing approaches have led to increased testing time and costs. Process maps can be used to develop realistic scenarios that capture the different decision paths in financial processes. These scenarios can then be used to design test cases, reducing the number of test cases needed while still ensuring adequate coverage. For one application tested this way, the number of test scenarios was reduced by 11-15% and test cases by 20-25%, cutting overall testing effort by around 20%.
Cost accounting systems should be a strategic partner in meeting your performance objectives. To do so requires maintenance and tuning - tasks that seem to have been forgotten. You've already made the investment in your cost accounting systems. Why would you not choose to utilize this important tool to its fullest advantage?
Offshore oil and gas organizations experience an average of $49 million annually in costs due to unplanned downtime. A study found that operators using a predictive, data-based maintenance approach experience 36% less unplanned downtime than reactive approaches, saving $17 million annually. While digitization can help reduce unplanned downtime through predictive analytics, most operators still rely on outdated reactive or time-based maintenance approaches. The study recommends operators adopt data-driven predictive maintenance using digital technologies to realize significant operational efficiency and cost savings.

Mining Cost Cutting Cycle and the ways to Avoid the Traps

The Mining Cost Cutting Cycle and Ways to Avoid the Traps
Summary
TSV Mining has often witnessed thatnot all cost cutting methods transfer well from site to site, and
some may have hidden traps that become detrimental to the longer term sustainability of a mine.
Background
As the mining industry tightens its belt due to costs exceeding cooling prices for many operations,
the cost cutting machine has kicked in yet again. Having been through this same Groundhog Day a
few times and seen the transitions from the overspending to the cost cutting phase of the cycle, we
have noticed several traps that mining operations can get caught by.
Working with clients whilst they were expanding during the boom time, we were able to
demonstrate the non-linear relationship between throughput expansions and costs. Contrary to
expectations of economies of scale, costs were actually going up exponentially with the increase in
production, not linearly. There were a number of well-publicised reasons for this, such as:
A requirement to move into high stripping ratio areas that could be avoided at lower levels
of production
Additional major capital purchases including processing plant upgrades and expansions
during a period of elevated capital costs
Higher freight costs as long term contracts were reset and where further production
increases required substantial below rail capital investment due to capacity constraints
being approached
Increasing supplier costs with the higher demand
However, there were also some less than obvious causes for the exponential increase in costs. Mine
plans that were being produced were becoming more and more aggressive as companies tried to
take maximum advantage of the boom. Creating a plan on paper was seen as the value that could be
achieved, disconnected from the real value in the pit. Operations were being stretched to a higher
intensity than had been seen before. On paper these plans looked to be quite achievable compared
2. 2Total System Value
to previous productivity levels, but when implemented, they tended to perform poorly.
When we were part of expansion projects, a difficult element was making sure the plans were
actually achievable. The difficulty was not in getting the plans to work per se, but rather convincing
the business that a lot of the methods used to increase production were merelyincreasing the risk of
the plan, and such risks would have negative consequences well beyond the value being chased on
paper.
We once calculated the odds of a more bullish productivity assumption being used for a medium
term plan: the change in assumption would allow a saving of approximately $10 million in order to
curb the rising expansion costs through a reduction in contractor stripping requirements. The odds
of a successful outcome were very low; less than 5% based on statistical analysis of previous
stripping output. We demonstrated that the downside of the attempted saving if the contractor
stripping was not able to be replaced by improved owner-operator performance would be a loss in
revenue in the order of $50 million that year (and site policies made it nearly impossible to prevent).
So there was a $50 million bet being made in order to achieve a $10 million windfall – in gambler’s
parlance it was a bet paying $1.20 the win, with less than 5% chance of paying off!
Another major cause of unmet planned targets was the implementation of new policies. Some of
these policies were required to ensure the sustainability of the operation; however many were
implemented for an isolated process without any analysis on the impact it was having on the overall
production system. The cost to the operation from the policies was not measured or understood.
The price and the demand for resources still remains strong historically, leading to companies
maintaining high levels of production, but needing to combat the unprecedented jump in costs.
Capital investment for a lot of mining operations has already been spent, and there still remains a
requirement to maximise the financial return on these.
5 Hidden Cost Cutting Traps
Some organisations are seeing the obvious benefits of cost cutting; it is hard to argue against cuts
such as renegotiating contracts with contractors and suppliers that were agreed during a “hotter”
market. Reducing overheads in areas that don’t add any value to the actual production chain is also
a clear winning move in the current environment. Improvements that clearly demonstrate increased
production out of equipment that allows for reduced contractor input or the ability to shut excessive
3. 3Total System Value
capacity is something that will pay off in any part of the cycle. However, there are always some
things to watch out for when looking for other cost cutting targets.
1. Watch out for the perceived benefits on paper
A short term cut can lead to long term devastation. As in the example of chasing the $10 million
saving earlier, there can be a large downside if it is not fully thought through and done properly. A
lack of understanding in risk or consequence contained in the mine plancan cause a false sense of
benefits being achieved. In our experience we have found the usual static, deterministic plans that
we are all use to, to be incapable of giving any information onrisk or consequences. Even the token
effort of completing a tornado plot at the end of the planning process really adds nothing to the
understanding because it is still based on a static plan, it doesn’t account for the interactions that
occur between production processes or show how the variability contained in the system effects
throughput.
Pressure on performance does not have to come from the mine plan directly; aspirational targets
can still be used as an operational incentive without the need to generate overly bullish numbers in
the base mine plan. Keeping the plan as close to reality as possible will ensure that all processes are
likely to be resourced “correctly” and sets a clear baseline.
If risk is to be increased in the plan, take risks that have high reward with minimal downside and
make allowance for that risk within the plan through discounting.
2. Are site inventories being reduced, making the site more vulnerable?
Just about all processes at an operation will have some form of inventory. In the production area
there can be:
Topsoil cleared
Drilled inventory
Blasted inventory (both waste and broken stocks)
Prestrip inventory
Coal/ore uncovered inventory
Pre-processing (raw coal/ore) inventory
4. 4Total System Value
Product/concentrate inventory at site and in the logistics chain
If there is an ability to reduce these inventories (and yes, a consistent increase in performance of a
process which is stable both statistically and relative to plan, can allow for significant reduction in
these), this can be a successful cost reduction method through savings in working capital. However,
reducing inventories to reduce costs without addressing variation can lead to unwanted
consequences.
Inventories protect the system throughput and are critical in handling normal variability in output as
well as negative unplanned events (and all unplanned events are negative, when was the last
unplanned event in your production system that was a boost to the for throughput?). Events tend to
be unplanned as individuallythey are infrequent; however the likelihood of one or more of these
events occurring is almost certain in a year. Inventories enable an operation to handle these events
and sustain throughput. Any cost saving measure through reducing inventories should have a very
good handle on the variability of different processes and the potential for negative events to impact
the plan such as wet weather, major equipment failures, geotechnical incidents, or an error in
design.
Any operation will incur negativeunplanned eventsat least once a year. It is not economically viable
to significantly lower the chance of these events occurring.
3. Some changes will happen gradually and may be missed
We’ve all heard the boiling frog analogy; if you put a frog in boiling water it will leap out right away
to escape danger but if you gradually heat the water from a cool temperature, the frog will not
notice until it is too late.
The open cut mining environment tends not to detect change well because the production cycle is
much longer term compared to the manufacturing industry, resulting in gradual change that is not
easily noticeable. If the main key performance indicator tracked is final throughput, and only
minimal focus is put on leading indicators such as inventories (and not just final product inventory),
then there may be no warning that a process is about to become a constraint for the
system.Inventories will always go up and down as they smooth out the inevitable fluctuations in the
system; it is what they are there for. What they should not do is continue downwards, unplanned,
for an extended period of time. When this occurs, a new process will eventually start to hold up the
5. 5Total System Value
system. At first the occasional hold up will occur, gradually increasing until it becomes a constant
issue. If inventories have decreased in a number of processes, the situation may become even worse
with the constraint floating across the system, making it even harder to find where best to apply
limited resources to remove the constraint and lift overall throughput and a production system that
is impossible to get under control because of its unpredictability.
Changes to constraints will not happen overnight. Observing unplanned, consistently dropping
inventory is a lead indicator that the current production is unsustainable with the current application
of resources.
4. Processes in the operation previously considered minor and therefore unscheduled have
become more crucial and are very sensitive to resource changes
With the higher intensity being included in mine plans, potential issues can be missed. One major
issue we have seen at mining operations (and it is becoming more and more common) is that some
processes are no longer needing to be resourced based on the size of the combined tasks over time,
but rather the time that will be available for the process to be performed for each individual task. As
production increases in the same footprint, the time available for supporting tasks such as drill prep,
drilling, blasting, etc actually reduces exponentially, not linearly (if you don’t believe this, picture a
single digging unit that moves across four dig areas; now consider two diggers over the same four
dig areas and compare the amount of time that a digger is away from an area to allow time for
support activities: production doubles but time for support activities reduces by two-thirds, not by
half). This can cause untracked and unscheduled processes to become constraints with very little
warning. It is only obvious when the schedule is run with production targets aligned with actual
performance and with all processes that consume time in the operation being scheduled, no matter
how minor they might have previously seemed. These supporting tasks may need substantial sprint
capacity (anathema to the cost cutting drive) if they are to complete tasks within the time available
and maintain plan stability.
Supporting taskscan stop throughput just as easily as major production tasks, however it is relatively
cheap to prevent. At most operations they can actually be responsible for some of the lowest
marginal cost throughput on site.

5. Using utilisation to understand resource requirements can be dangerous
There may be a poor relationship between process utilisation and resourcing requirements.
Utilisation works well as a short term indicator when working on a task; however it can be a poor
method for calculating long term resourcing requirements. This is the case when tasks need to be
completed in a narrow period of time and there is standby time between these task windows.
Generally this is the case for most minor tasks on site, such as small excavation tasks, drilling
preparation, drilling, grade control, blasting and pumping.
A simple method of demonstrating the potential size of delays when long term demand is used
rather than focusing on short term peak loads is to use Queueing Theory, first developed by Agner
Erlang.
Let’s use an example of a blast crew:
As other processes release jobs they become flagged for the blast crew to complete. When
resourcing a blast crew based on the overall tonnages they are required to complete over a
sustained period (such as a budget year), the assumption is made that they can level the tasks – ie.
as long as their capacity is higher than the overall requirements, then the blast crew should not hold
up any process.
If we assume that on average two blasts a week are released with an average 400t per blast, and the
blast crew has a loading capacity of 1,000t per week including two tie and fires a week. What will
this look like?
Case A: D/D/1 (deterministic task arrival / deterministic task service / 1 blast crew)
Average blasting requirement = 400t
Average blasting task released = 2 per week (or arrival rate of 0.286 blasts per day)
Blast crew capacity = 1,000t / week (or a service rate of 0.357 blasts per day)
Blast crew capacity utilisation = 80%
Average time released tasks wait for blast crew
But we know that tasks will not be released at equal intervals each week. Let’s give the release an
exponential distribution around the arrival of these tasks:
Case B: M/D/1 (random task arrival / deterministic task service / 1 blast crew)
Average blasting requirement = 400t
7. 7Total System Value
Average blasting task released = 2 per week (or arrival rate of 0.286 per day, on average but random)
Blast crew capacity = 1,000t / week (or a service rate of 0.357 per day)
Blast crew capacity utilisation = 80%
Average time released tasks wait for blast crew
So blasting tasks on average are now waiting 5.6 days on average before the blast crew will get
around to them.
Next, let’s give the blasting process a distribution. Both the blast crews and the size of the tasks will
have a distribution, for simplicity we will use a normal distribution around the service rate of the
blast crew.
Case C: M/G/1 (random task arrival / random task service / 1 blast crew)
Average blasting requirement = 400t
Average blasting task released = 2 per week (or arrival rate of 0.286 per day, on average but random)
Blast crew capacity = 1,000t / week (or a service rate of 0.357 per day, on average but random)
Blast crew capacity utilisation = 80%
Average time released tasks wait for blast crew
NOTE: Though we have used an exponential distribution for arrival time and normal distribution for
the blast crew/task size – this is just a simple example to demonstrate that utilisation of a process is
not always right. Distributions would differ site to site.
So something like the blast crew can be sensitive to an operation, particularly one working on a time
size requirement, as a blast crew at 80% capacity utilisation has jobs waiting 11.2 days on average to
be processed. For a high intensity operation that is trying to achieve quick strip/block turnaround,
this could cause a significant loss in throughput.
Say if this blast crew was cut back due to high costs, and the expectation was to get 90% utilisation
8. 8Total System Value
from the remaining crew. In this case using the same calculations as previous, the average wait time
for a blast will end up being 28.4 days, not much of a saving, but a potential large loss in throughput
and revenue.
The blast delay here is just an average. During peak blast demand times the wait could be
substantially higher. It is easy to see how these delays could affect throughput if the blast window is
narrow, severely affecting downstream processes such as stripping. In order to correctly resource all
processes in the operation, all time consuming activities must be scheduled dynamically.
5 Sustainable Solutions when Cost Cutting
There are numerous methods to cutting costs that are sustainable, such as:
Renegotiating contract rates to a lower price
Removing non-value adding activities and resources
Delaying expansion projects
Increasing process productivity
However we thought we would give some different solutions rather the more traditional ones:
1. Check policies and improvements for individual processes and see if they truly benefit the
system
Localised improvements for a process can quite often be to the detriment of the system. If the value
is only measured at the process without analysing upstream and downstream processes, it may not
be aligned with the revenue of the operation. Operating standards/requirements also tend to
accumulate over time.
An example of this is a localised improvement that reduces the number of trucks needed to haul coal
by breaking up the long hauls into shorter segments, thereby reducing the peak loads of haulage.
This could result in a saving of $5 million per year. However, undertaking a system-wide approach to
improvements would reveal that more coal rehandling increases fines generation, creating an
overload in the fines circuit of the CHPP and dropping the coal yield from these areas by 8%,
reducing revenue by $17 million per year. In addition to the loss in coal produced, there could be
other downstream issues, such as reducing handleability in the logistics chain or client concerns with
9. 9Total System Value
the increased fines.
All process improvements and policy changes should undertake a system-wide analysis to ensure
that all unintended consequences are found and examined.
2. Look at opportunities to reduce the variation in the processes
At TSV Mining we analyse six main sources of variation that are typically found within the
commodity value chain of the open cut mining environment. Reducing variation in the system is
always possible. Interrelationships between variation sources have exponential effects on any
operation. Some reduction can be relatively cheap and provides for the sustainable cost reduction in
many areas through a reduction in the required sprint capacity or the inventory.
Some examples of reduction in system variation include:
Normalising the length of stripping circuits by planning hauls and dump locations more
thoroughly, ensuring that the operation is hauling “long dirt” to the short dumps and “short
dirt” to the long dumps
Improving grade control practices
Upskilling of frontline supervision to a consistent standard
Improving water management capacity to reduce the effects of future weather events
Balancing block sizes so that coal/ore is released on a more consistent basis
Improving quality control in the processing area so that penalty components are closer to
the customer specification while still not getting penalised
Understanding the sources of variation and how the systems reacts to changing variation is one of
the largest opportunities to reducing costs in most operations.
3. Look at getting the right inventories in the right locations
There is a huge amount of working capital tied up in inventories. Getting inventory levels and
locations right ensures the system throughput, but getting them wrong is simply tying up working
capital or reducing the potential throughput of the operation. Often when working with clients we
find that risk mitigation strategies have inventories in low value locations (usually because these are
the areas where inventory can be held more easily, regardless of whether it adds value), when
10. 10Total System Value
alternative locations can reduce costs significantly and improve the risk mitigation.
It is not just overall quantities of inventories that need to be monitored; the right quantities must be
in theright locationsin order to be cost effective.
4. Customise the cost reduction for each operation
Anchoring is a cognitive bias that affects us all, where we tend to overly focus on what has worked
previously, both in our personal experience and what we have seen work for others. However, no
two operations are the same, and taking a solution from one operation to another may have a
detrimental effect if it isn’t considered whether the reasons for the solution working elsewhere are
still applicable in the new environment.
Operations can have a sustainable cut in costs in the right areas. But assuming that all sites are the
same, and using the same technique across the board can be fraught with danger and actually cause
costs to increase in certain situations.
Process improvement resources are always in scarce supply, no more so than in the current
environment. Therefore it is crucial that a “boil the ocean” approach is not taken. Time should be
taken to identify the constraining process that is holding back overall throughput and then
commitment made to not make cuts in this area. All process improvement resources should then be
targeted at the one constraining process with a laser-like focus.
Cost-cutting can then be applied in other areas where there is excessive capacity (be sure to
understand what excessive is), with a scalpel, not a broad brush. However, each cut should consider
the effect on the rest of the operation. Decisions should be made considering the operation as a
complete system, not as a group of siloed processes.
Targeting areas to cut costs where they will not impact throughput is of high importance, and may
not be where you would like to cut. We have seen damaging cuts made to the productive capacity of
a process that was the main capacity constraint of an operation just because 50% of the site’s costs
were in that process.
Always customise the cost cutting for each operation as small differences between two operations
can cause big changes in where the focal areas need to be to improve throughput and reduce costs.
11. 11Total System Value
5. Look at incremental, not overall process costs
When there are multiple processes required to move material, with cost analysis changing the
process from one to the next, the costs need to be analysed on anincremental basis. Whether it is
moving from dozer push to excavator, increasing cast, choosing the dragline horizon with prestrip, or
adding equipment to an excavator circuit, overall process costs will not give a clear picture.
As with most things discussed here, incremental costs are not linear; they again go up exponentially
as productivity deteriorates exponentially: raising the dragline horizon will go through larger step
changes in rehandle (increasing rehandle exponentially), dozer push productivity will decrease with
longer and steeper uphill pushes (productivity deteriorating exponentially), the benefits from
increasing powder factor to achieve a higher cast or improve diggability will decay exponentially,
adding more trucks to a circuit will have a exponentially decaying benefit in additional throughput.
Overall process costs hide exponential cost increases.
Bringing it all together
Short term cost reduction benefits can have many hidden traps. There are many aspects of an
operation where sustainable cost reduction can be undertaken. In this paper there are several
underlying themes:
Always look at how the system is reacting to change, not just the individual processes
Inventories will hide potential throughput issues for a period of time.
Any inventory contained within the system that constantly deteriorates is a lead indicator
that current production levels with current application of resources is unsustainable
Most elements in mining do not change in a linear fashion, they tend to change
exponentially
Traditional methods of measuring resource requirements may no longer work
Keeping these themes in mind when looking for opportunities to cut costs and increase throughput
will have you well-armed in avoiding many of the traps and pitfalls we have mentioned here.
