Longwall Top-Coal Caving: A productive and efficient alternative. Longwall mining is one of the most productive ways to produce coal, but longwall mines have trouble efficiently mining seams higher than 6 m (19.6 ft). Longwall Top-Coal Caving can more than double the resource recovery rate of normal longwall equipment working in high seams.

Case Study - Remote Control of Longwall Mining

2010-1-11  "Longwall" mining differs from "Room Pillar" mining in that the mine roof is expected to fall when operations are concluded in a particular area of the mine. For this reason, roof supports are not as extensive at the working mine face. This holds obvious danger to the miners operating at the fine face using the mining machines called "shearers".

Longwall Mining in Seams of Medium Thickness

2019-9-4  In continuous mining, a machine known as a continuous miner cuts the coal from the mining face and deposits it directly into a haulage vehicle; an efficient technique that obviates the need for drilling and blasting. Room-and-pillar mining in low seams is generally less efficient than longwall mining because as much as 50% of coal is lost.
