Stability Analysis of Pillar System during Room and Pillar Retreat Mining with Three Coal Seams
Multiseam interactions are a major source of ground and pillar instability in many underground coal mines. The objective of this study is to propose a method for determining the optimal parameters of a panel layout for the room and pillar retreat mining with the rational extraction ratio and stabili...
