Ground Control Design For Highwall Mining
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 plans for highwall mining should specify hole width, web pillar width, barrier pillar width and number of holes between barriers.
Longwall Mining Overview | Introduction | underground COAL
Longwall mining systems are capable of producing significant outputs from a single longwall face – 8 million tones per annum or more. When operating correctly the coal is mined in a systematic, relatively continuous and repetitive process which is ideal for strata control and for associated mining operations.
Longwall Mining
Longwall mining machines are about 800 feet (240 meters) in width and 5 to 10 feet ( to 3 meters) tall. Longwall miners extract "panels" rectangular blocks of coal as wide as the mining machinery and as long as 12,000 feet (3,650 meters). Massive shearers cut coal from a wall face, which falls onto a conveyor belt for removal.
