| Abstract: | Based on the engineering geological conditions and mining conditions of 2305 fully mechanized coal face,and by using the numerical simulation （RFPA,Rock Failure Process Analysis）and field measurement method,this paper makes deep analysis on the failure and movement laws of the false roof,immediate roof and basic roof after the mining of shallow seam,providing some theoretical bases for guiding and evaluating the control of surrounding rocks. |
