Abstract


In this paper, taking the Tiger bench mine special thick coal seam mechanized caving mining as an engineering instance, through numerical simulation research, we systematically analyzed how thick coal seam mechanized caving mining induced surface subsidence basin magnitude and scope, and researched impacted characteristics and destructive effect of the surface deformation of large fault zone.
