Mechanical behavior and stability control of regenerated roof in long wall stratified mining of thick steeply dipping coal seam
This study focused on the stability control of roof in long wall stratified mining of large dip angle thick coal seam. Taking Panbei Coal Mine in Huainan as an example, the effect mechanism of water content, compression ratio and grain size grading on the compression characteristics of gangue is ana...
