Abstract: Preliminary analysis of rules and control mechanism of surrouding rock movement of backfill mining and entry retaining with super-high-water material is made combined with the actual application situation of this technology. Adopting numerical simulation to simulate the rules of surrounding rock movement of backfill mining and entry retaining for goaf filling rate of 70%, 80% and 90%, it shows the stress and deformation of surrounding rock decrease reduces with the increase of goaf filling rate.The application in experimental working face has been made that the roof and floor convergence of roadway is within 60 mm, and the deformation of roadway’s sides is within 30 mm in field measurement, the support pressure of bag filling body is less than 2.5MPa, so it can be used for a long time so as to provide technical reference for the similar situation.
