Deformation and Failure Mechanism of the Lower Roadway in a Close-Range Residual Coal Pillar Area

Deformation and Failure Mechanism of the Lower Roadway in a Close-Range Residual Coal Pillar Area

The Tashan coal mine is selected as a case study to determine the deformation and damage mechanisms of the lower roadway in a close-range residual coal pillar area. Roof drilling peephole technology is applied to detect the damage to the roadway roof surrounding rock. A boundary invisibility equatio...
