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".
