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 [.]
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
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.
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.
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

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.
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 ...
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.
