Continuous miners, used primarily in 'room and pillar' mining and also to prepare roadways in a 'longwall' systems, have incrementally improved over the last 20 years (Fig. 7.11).But they are not advancing in automation as quickly as longwall equipment, with the exception that they are more often remotely controlled by an operator, rather than by an operator sitting on the machine.
The longwall room and pillar mining method is a mining method that combines room and pillar mining technology with the longwall mining layout. The coal pillar and the mining width are designed using the room and pillar mining method, and the optimum panel size is determined by the longwall panel layout—"longwall panel layout with local shortwall mining."
