Highwall mining is another form of mining sometimes conducted to recover additional coal adjacent to a surface mined area. The method evolved from auger mining but does not meet the definition of surface mining since it does not involve the removal of overburden to expose the coal seam.
ADDCAR Systems LLC is an international highwall mining (HWM) specialist based in Ashland Kentucky, USA with over 25 years experience operating HWM systems in the .
Highwall miners link underground and surface mining operations by extracting coal from exposed horizontal seams in openpit mines. This is done via a mobile system that contains a continuous miner controlled from the operator''s cabin, a retractable conveyance system, and a vertical conveyor that handles and stacks the coal for transport.. The point at which the cost to remove the overburden ...

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine a pit, and the ...
Highwall mining is a hybrid of surface and underground mining technologies that is used to recover coal that is otherwise uneconomical due to: Increasing open – cut strip ratios Reaching pit limits with available coal in the barrier pillars Protected surface features ( rivers, streams, archaeology) Inadequate panel length for a punch long wall Mining [.]
Auger Mining System Extracting Coal from the Highwall of Surface Mine As coal is produced from the auger mining machine it is stockpiled and loaded into haulage trucks. Much more common than auger mining as a means of secondary coal production on surface mines are highwall mining systems.
Examine and monitor highwall often. Follow ground control plan. Train miners to recognize hazardous highwall conditions. Scale down or support the hazardous highwall areas. Keep drill and other mobile equipment operators away from highwall face or highwall hazards by positioning them in safe locations. Employ mining methods that will maintain wall,
repairs to the Highwall Mining equipment may be made under the FOPS, including bit changes on the continuous miner. Major repairs to the mining equipment may be completed during daylight or nighttime hours. Adequate lighting shall be provided for work areas as per 30 CFR (e).
Mar 13, 2012· High Wall Mining Technology• Highwall Mining is a remotely controlled mining method, which extracts coal from the face of a coal seam under a highwall in a surface mine, which has reached the final highwall position due to uneconomic stripping ratios Or due to local constraints which limit further surface mining.• The coal left in the High ...
GROUND CONTROL DESIGN FOR HIGHWALL MINING R. Karl Zipf, Jr., NIOSH, Pittsburgh, PA Abstract Highwall mining is an important surface coal mining method, and it may account for approximately 4% of total coal production. Highwall stability is the major ground control related safety concern. Ground control
The selfcontained Cat highwall mining system offers an innovative method for extracting coal from exposed seams in a multitude of applications. Whether you''re operating a trench, open cast or contour mine, the Cat highwall mining system can extract coal affordably and safely: • Open cast: Highwall mining is used to mine coal from ...
The machine is generally operated from a bench that is created by the removal of overburden material and coal by way of contour surface mining around the perimeter of a coal seam. Other highwall applications include previously augered areas and trench mining.
Commonwealth Mining LLC is a Highwall Mining Services Co. that has Operated Highwall Miners in Ohio, West ia, Kentucky, Alabama and ia. We have provided consulting for Highwall Mining Operations in Australia and India as well as currently providing consulting services to Highwall Mining Companies throughout the United States.
years at a highwall mining operation was due to highwall col lapse. have also been numerous nearmisses, several of which have involved extensive damage to equipment. In the central Appalachians, where the majority of highwall mining occurs in the , hillseams are the most prominent geologic structures that affect highwall stability.
Linking underground and surface mining operations, the CAT highwall mining system is a testament to versatile mining equipment. It offers a safe and innovative method for extracting coal from outcropping seams in a multitude of applications.
Since 2011, 16 metal and nonmetal miners have died in accidents involving machinery and nonhaulage mobile and quarry equipment, and many more have been seriously injured or disabled. Of the 16 persons fatally injured, six were supervisors and three were contractors. Seven miners died when they were struck by the equipment they or a coworker were operating, four miners
Mar 14, 2016· Do not dig into the toe of a high wall. Increase the number of benches at each high wall to catch falling material. Use CB radios to keep equipment operators informed of high wall conditions. MSHA Rules To Live By – High Wall Safety In Surface Mining . There are also several applicable points from the MSHA Rules To Live By initiative.
