Effect Analysis on Destroy Form about Overburden by RRL and RRM on the Condition of Shallow Coal Seam

摘要：

The article, based on locale observation, gave the expression on different the ratio of rock and loading (for short RRL) and the ratio of rock and mining (for short RRM) and destruction forms by analyzed pressure appear character on shallow coal seams. It applied RFPA numerical simulation software to simulate 20601 face in DaLiuta coal mine, simulation result showing: RRL and RRM had important function for overburnden destroy form, and proved the correctness and rationality between RRL, RRM and the overburden failure modes. It might be useful to mining under the condition of shallow coal seam.
