@@@@The experiment research of the filling to control the surface subsidence based on the method of similar material simulation was done to simulate the movement of the surface and the strata of the working face. Three different strength filling material were used to filling the mining working face in processing. The movement regulation of the surface and the overlying strata were observed. The movement regulation of the surface and the relationship between the strength of the filling material and the coefficient of the surface subsidence and the relationship between filling space and the fill time were obtained. The scientific basis was provided to solve the goaf filling mining.
