The document discusses highwall mining, which involves using an unmanned continuous miner to extract coal seams exposed on the face of a pit or quarry. Key points:
- Highwall mining uses a remote-controlled cutter module pushed into the seam by push beams to mine and transport coal without personnel underground.
- The Bucyrus Highwall Mining System allows versatile extraction from trench, open cast, and contour mines using a self-contained machine operated by 3-4 crew.
- It offers affordable and safe coal mining while producing 40,000-110,000 metric tons per month depending on seam height.

Overview of Highwall Mining. A small Pictorial Demonstration files. New Technology. Solution to unreachable beded deposit. Highwall mining is a remotely controlled mining method which extracts coal from the base of an exposed highwall. The method has the advantage of low capital cost and less lead time compared with a full underground mine, while being capable of producing in excess of 1 million tonnes per system per year.

Electrical power transmission has replaced mechanical power transmission everywhere except very shortest distances. What is worth remembering, however, is that from the 16th century through the industrial revolution to the end of the 19th century mechanical power transmission was the norm – even for long distances.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

3. Bucyrus Highwall
Mining System
The industry-leading Bucyrus Highwall Mining System is a new,
low-cost addition to traditional mining methods. The system
can produce 40,000 to 110,000 mt (44,000 to 121,000 tons)
of coal per month depending on seam height. Capable of full
operation with a three- to four-man crew, the Bucyrus Highwall
Mining System averages 27 to 36 mt (30 to 40 tons) per man-
hour. Innovative technologies such as an effective cutter module
and powerhead assembly contribute to the system’s
outstanding productivity.
The Bucyrus Highwall Mining System is designed for easy
maintenance with a reliable, straightforward design and a
comprehensive diagnostic system with troubleshooting
capabilities to enhance uptime. Able to be disassembled in
modules, the system can be transported over long distances.
Everything about this highly efficient highwall mining system is
engineered to provide excellent return on investment.
Machine Service
& Support
Every Bucyrus Highwall Mining System is backed by 24/7
support from our highly skilled and experienced staff. Our large
warehouse is fully stocked with spare parts to ensure the highest
levels of machine uptime, and service and parts back-up can be
tailored to your needs.
4. Proven Cutter Module
Bucyrus offers two electric cutter modules: a low seam cutter for
seams 0.76 m – 1.62 m (2.5 ft – 5.3 ft) in height, and a high seam
cutter module to mine 1.30 m – 3.05 m (4.3 ft – 10.0 ft) seams.
The cutter modules are interchangeable and quickly attached to
the powerhead assembly. The cutting cycle is fully automated,
yet allows the operator to manually adjust the machine function
using an ampere reading as the coal seam varies. This proven
technology allows the cutter module to accurately follow the coal
seam and produce a clean product.

5. Excellent Mobility
The Bucyrus Highwall Mining System is an agile, self-propelled
machine that operates on contour benches as narrow as 18 m
(59 ft). It trams easily from entry to entry and discharges coal in
tight spaces.
An optional right-angle conveyor system discharges coal on the
right or left side on narrow benches. It can also discharge onto a
stacking conveyor system, where coal is moved to the center of
the bench for stockpiling large volumes.
Four heavy-duty, hydraulically powered tracks articulate Tram mode
independently in two operating modes — mine mode and tram
mode — and can rotate the machine 360°, which improves
maneuverability in congested areas. Mine mode is used for
moving parallel to the highwall, while tram mode is used when
moving from pit to pit.
Operator Comfort
The Bucyrus Highwall Mining System is equipped with a
comfortable air-conditioned cab that offers a full view of
the mining operation and the highwall. The full-suspension
operator seat and the two user-friendly touch-screens create an
ergonomic workplace, placing controls and system information
at the operator’s fingertips.
Mine mode
User-friendly touch-screens
6. Dependable Push Beams
Bucyrus push beams are 6 m (20 ft) long rectangular reinforced
steel box structures joined together to form a string, which
connects the highwall mining system to the cutter assembly. The
push beam string is the backbone of the machine; pushing and
pulling the cutter module in and out of the highwall with retract
forces up to 363 mt (400 tons) at 345 bars. The push beams also
transport mined coal and support the hose chain that supplies
control and power to the cutter.
Moving coal inside the push beam (via a pair of screw conveyors)
protects the coal from contamination and the moving mechanical
parts from rock debris, resulting in higher availability. Other
Bucyrus push beam advantages include:
Push beams n A strong method of attachment that is secured and
disengaged quickly
n A horizontal hinge design that allows the string and cutter
to navigate through coal seam rolls and undulations
n Structural rigidity that ensures mining in parallel drives
n A simple design free of electrical and hydraulic connections
n Push beams that can be stacked six high for storage
in narrow worksites
Robust Reel & Chain
A steel-armored hose chain stores and protects all electric power
cables, hydraulic and water lines, and the control cable to the
cutter module. The hose chain is automatically unrolled and
retracted on a reel during mining.
Control System
with Diagnostics
The Bucyrus Highwall Mining System’s operation is controlled by
a Programmable Logic Controller (PLC) which provides reliable
performance for greater uptime. A comprehensive diagnostics
system, including troubleshooting assistance, streamlines
maintenance procedures.
Anchoring System
Two drills mounted on the front of the machine are used to drill
into the pit floor up to 2.5 m (8.2 ft). High-strength pins are then
inserted through the base frame into the pit floor to help stabilize
Reel and chain
the machine and to maintain its accurate position, even under
tough pushing and pulling conditions.
7. Easy Equipment
Relocation
For quick relocation over long distances, the Bucyrus Highwall
Mining System can be taken apart in modules. Rapid disassembly
and reassembly is facilitated by convenient hydraulic and
electrical connectors, and all modules are sized for transport
using regular public roads. Depending on local conditions,
and without disassembly, the system can also be transported
between sites and without disassembly, by heavy haul trucks.
Specialized Training
Our operational and technical training covers every aspect of the
Bucyrus Highwall Mining System. We offer a two-week training
program from our Beckley, West Virginia, USA, facility to new
customers and to existing customers as a refresher. We can also
offer a tailored program at your location.
