Room and Pillar Mining - an overview ScienceDirect Topics

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.
