Abstract

The movement law of overburden strata in backfill mining face was studied, by the method of similar material simulation, on the background of the paste filling mining in Daizhuang Coal Mine, and in consideration of change of filling body strength with time. The results showed that the immediate roof by caving method can be converted to basic roof by full mining and full backfill, and they can keep force transfer in advance direction. The roof structure of “coal pillar-coal wall” became the roof structure of “coal pillar-filling body-coal wall” in the process of fill mining, which can control mining subsidence effectively.
