Glencore Coal Assets Australia has grown to be the largest coal producer in Australia with open cut and underground mines spread throughout NSW and Queensland. Glencore has very high regard for engineering and has sponsored the development of statutory mechanical engineers in NSW for more than a decade. This presentation looks at where Glencore stands in relation to safety and engineering, how this is managed within Glencore Coal, and some of the key challenges, direction and lessons.
Clint has experienced the evolution of workers' personal risk management from being self-managed to a prescribed personal risk assessment process and company risk management. This has gone from a process not involving or understood by the worker to a prescribed process with the worker having direct involvement and influence in managing hazards at a mine.

Safety & Quality Aspects in '3-S' System of ConstructionSandeep Jain
‘3-S’ system is the brand name of prefab building construction system fully developed and perfected by B.G. Shirke Construction Technology Pvt. Ltd. After years of strenuous R&D supplemented by extensive field trials. ‘3-S’ PREFAB components are erected, aligned and connected; on site using SCC i.e. Self-Compacting Concrete of M30 grade screeding along with secured embedded reinforcement.
The things that we tried to know through this project include-
• Understanding the 3-S system of construction.
• How it has improved the safety and quality of construction?
• What are the loopholes of this method pertaining to safety and quality control?
We started with the study of Quality, Environment, Health& Safety policy of the company. Knowing the basics of the 3-S system of construction we went ahead with the 4-stage process consisting of manufacturing of components, storage and curing, transit to site & erection and assembly.
In manufacturing of various components like shear walls, beams, columns, slabs, staircase etc., other than the manufacturing techniques of 3-S system we focused on its safety and quality parameter. After the manufacturing bay we went to the storage & curing yard with a view to understand the safe storage practices and then moved ahead to get an understanding of safety in transit of cured components fromyard to the erection site. And last but not the least we learned the safe erecting practices and quality control while erection and assembling the components at site. The topics covered are:
• Safety management in:
Manufacturing& storage phase
Transit
Erection phase and
Personnel safety
• Quality assurance in:
Manufacturing and
Erection phase.
After knowing this technology we now tried to compare the pros and cons over the conventional system of construction.
Pros:
1. Considerable reduction in time of Construction
2. Controlled work environment
3. Improved quality control and safe
4. Mass production process
Cons:
1. Can only be used for repetitive units
2. Improper joint may cause leakages
3. Accumulation of stresses
4. Requirement of skilled labor in erection
5. High initial capital investment
Large Diameter Sanitary Sewer Condition Assessment Package 5Fairfax County
This project obtained condition assessment information for approximately 47,000 feet of 18 to 42-inch diameter sanitary sewer pipes and 197 manholes located near Herndon, McLean, and Annandale. The inspections were performed using multi-sensor (Closed Circuit Television (CCTV), sonar, and laser) inspection technologies to identify internal defects. Defective sewers were identified for repair, replacement, or rehabilitation under future contracts. This project was substantially complete on January 15, 2021.
The death of a truck operator in the USA in 2018 at a Peabody mine as a result of a fire highlights the importance of installing fire suppression systems. Firestorm has been involved in the world's largest retrofit of fire supression systems on buses. While buses may be considered simple for fire protection versus a mining machine, buses can carry up to 100 passengers and typically there is a lack of mechanical protection with the majority of the body made of fibreglass, wood and plastics that burn very quickly and are highly toxic. The risk for multiple deaths is therefore a much higher factor compared with a mining machine with one operator. The risk assessment required in AS5062-2016 needs to consider the egress paths available for an operator/passenger to safely evacuate the machine and consideration for actuators and fire extinguishers along this path.
Changes to laws in 2016 required the removal of PFAS and PFOS in both Queensland and South Australia with penalties noe effective for non-compliance. Several NSW mines have been put on notice by the Environmental Protection Agency (EPA) to prevent further contamination of waterways. Firestorm is now moving away from exposing our own people to PFAS/PFOS systems to ensure we are providing best practice even though laws are not yet in place for NSW. This presentation looks at what it means if you choose to move away from PFAS/PFOS systems.
Every organisation has a culture, and every culture is different. Every organisation has a culture around safety, which can often conflict with the culture around hydraulic systems.
Since the inception of the NSW Resources Regulator's MDG 41 - Guidleine for fluid power safety at mines there has been an explosion of interest in the safety of hydraulic systems. From the early days of MDG41 there was a significant drop in hydraulic incidents reported to the Regulator.
Recently there has been a spike in fluid power-related incidents around the industry, which suggests there is a disconnect between the perceived and real dangers of fluid power systems. As we now see the industry growing and less experienced workers joining the industry we must ensure that we demonstrate the correct culture when dealing with hydraulic systems.
Liberty Industrial was engaged by Glencore to complete the demolition of a former coal preparation plant on a redundant mine site in Teralba NSW. While the mine was non-operational and formerly underground, many of the mine systems, plant pass-in and permitting requirements were based on on the site being an operational underground mine. Both Liberty Industrial and Glencore worked together during the planning phase to ensure that both parties understood the work, the design-related aspects and aspects of the Glencore systems that were not appropriate for this type of work. The teams worked together to develop a risk-based approach that satisfied the Glencore internal systems while maintaining efficient execution processes.
This presentation outlines the approach taken by EnviroMist, in partnership with the University of Wollongong, to develop effective dust suppression systems for the mining industry.
A thorough approach using real-time dust monitoring, airspeed monitoring and material testing will be presented as the first step to define a dust problem. Following that, the use of modeling techniques such as CFD and DEM in combination with laboratory test data allows for the variables defining a problem to be investigated.
Finally, a solution can be proposed that is specific to the conditions of the application, based on the data collected and the results predicted from the simulation modelling. The presentation includes various case studies which demonstrate the effectiveness of this approach.
This presentation runs through case studies illustrating why machine failures are an invaluable source of knowledge. Yes, it comes at an expense, downtime, repairs and can have a significant impact on safety. However, it is the key lessons from a failure investigation that drive continuous improvement and, with it, commercial success and an environment where safety is paramount.
The studies draw on the concept of the price of non-conformance and why solely focusing on commercial short term gain can ultimately lead to long term pain. This is particularly true for critical assets that can affect production and safety if something goes wrong.

MNM Serious Accident Alert
On April 11, 2018, a miner received serious injuries when he was struck by a piece of
metal floor grating. A construction supervisor stepped on a section of metal floor
grating. that was unsupported and unsecured on one edge. The grating, which
weighed over 100 lbs., tilted, fell through the opening it was supposed to cover, and
struck the miner 25 feet below.
Best Practices
• Ensure that floor gratings and covers installed over travelways are substantially
constructed, fully supported, secured in place, inspected regularly and properly
maintained.
• Inspect metal structures located in wet or corrosive environments frequently to
identify
deterioration that may present a safety hazard.
• Evaluate the integrity and support strength of any cover that was not designed as a
walkway
prior to walking on it. Provide and maintain a safe means of access to all working
places.
• Restrict access to covers over openings not specifically designed to serve as
travelways. Provide readily visible warning signs that clearly display the nature of the
hazard and any protective action required.
• If the travel surface integrity is unknown or cannot be readily confirmed, ALWAYS
wear fall
protection.
This alert can be posted on bulletin boards, used in safety talks, or given to miners
and contractors as a hand out.

housekeeping/valid inspections/verification of inspection standard.
Position of CO alarms
• Oil drums – not on bunds, damaged, positioned where can be
damaged
• Refuelling bay - Fuel pods spillage (200 litres), rubbish, lack of
preparation/standards for temporary bays (stonedust/shotcrete/
concrete/drainage/ventilation), is it a temporary bay? (6 months – 18
months)
61
62. Fire and Explosion
Targeted Assessment Program
Repeated issues
• Surface fuel tank – build up of combustible material around
• Aluminium – splice gear not stored in steel container
• Lack of fire fighting equipment to suit the risk at key
infrastructure locations. Working off old legislative
requirement and MDG1032 for minimum. Consider the hazard
and provision/locate accordingly
• Smoking paraphernalia in a hazardous goods shed
62
63. Fire and Explosion
Other issues
• Conveyor guarding – access to rotating equipment, area guards full of
spillage, underpass transitions so don’t walk into return belt, brow
points
• Lifting gear - inspections out of date (hoarding,
fitter/rigger/dogman, static loaded), damaged and in service, etc
• Scaf tags – inspection out of date, no barricade to prevent use
• Lack of ventilation in workshop/diesel bay. If don’t want to waste air
into return then use vent tubes and air fan. Lack of ventilation not
classed as a control measure in the fire triangle
• Sump handrails – drive in sump, surface dams
• Gas cylinders not restrained from falling
• MECP includes management of items in Schedule 2
63
64. Fire and Explosion - Fitters
Broad generalisation
• They have better understanding of fire risks and controls
associated with diesels, conveyors and frictional ignition
• Lesser understanding of fire fighting system, except around
conveyors (deluge systems)
• Reasonable inspections of picks/sprays, water flow/pressure.
Often not recorded in Deputy report
• Require maintenance and inspection standards, such as:
o rules for numbers of picks/sprays before stop and change
o curtains and additional throat sprays
• Inspection shift – If one shift is doing all the maintenance and
daily inspections then diminishing skills on other shifts =
reliance

65. Fire and Explosion
Controls
• Identify biggest hazard in mine – Conveyor fires, Frictional ignition
• Identification of critical controls – top of head examples
o Conveyor pulley RTD’s
o Conveyor wander switch
o Conveyor inspection (idler tags, spillage clearance, etc)
o Equipment preuse inspection
• Verification of controls
• Equipment designed to prevent oil spills (bunded oil pods) are
