Abstract：In order to solve the problems of serious pollution of the ecological environment and the cultivated land occupation caused by the mining waste discharge and liberate the dull coal resource, a mining waste displacement concept was put forward according to the green mining concept. Based on the production specification of Xingdong Mine and through the full consideration of the stability of coal pillars, the roadway deformation and the filling sequence, a simulation scheme with different filling parameters was designed. The numerical calculation results showed that in the conditions of the roadway with the fixed size, the 4. 5 m coal pillar width and the 18 m minimum interval between the simultaneously filled roadways, the deformation convergence of the roadway was smaller and the mining rate was higher. The successful application of roadway waste filling technology displaced underground dull coal resource and produced greater economic and environmental benefits.
