There are many reasons for roof fall accidents, the root cause of which is caused by the activity of mine pressure in the mining process. The roof deformation occurs to varying degrees in the course of mining pressure activity. Firstly, cracks occur along the roof joints, resulting in the phenomenon of strata separation. At this time, if the roof protection is not appropriate, the quality of support is not good, the pressure continues to increase, and the rock deformation exceeds the elastic deformation limit, there will be fracture, collapse, slope or partial roof fall. From the analysis of the causes of roof fall accidents, some belong to insufficient understanding of objective things, while most are caused by poor site management.
