DEM fluid–solid coupling method for progressive failure
Under the condition of roof dewatering, the damage ratio of the coal seam rib is less than 65%, the area with greater damage (70–80%) is concentrated mainly in the fault zone, and the damage range of RSR is reduced. The results show that the roof dewatering scheme does not prevent the activation of fault around the roadway.
