Result Analysis of Ultra-close Spatial Stopes Overlying Strata Failure

摘要：

According to the similar materials simulation and numerical simulation method and coal seam of Daizhuang mine block 4300 , this paper uses simulation software FLAC3D to build three-dimensional model about the similar materials simulation and numerical simulation method, excavates 3upper coal seam step by step, then, excavate 3lower coal seam Step by step after overlying strata stabilizing. It gets overlying strata every . Excavation stage failure and distribution feature about circle of stress and analyzes movement law after exploiting 3upper coal seam and movement law when exploiting 3lower coal seam.
