Separate layer feature in overlapping mining overburden strata

摘要：

　　Deformation-failure of overburden strata of overlapping mining is more complex than caving of monolayer.On the purpose of getting the development law,the authors work through the overburden strata geological characteristics with analysis of well-measured and drilling television,simulate the deformation-failure of roof overlapping face with discrete element model.And we can obtain the laws of deformation-failure of overburden strata of overlapping mining,which can effectively guide coal mining roof prevention and control work.Of overlapping mining.
