摘　　要：基于矿区煤层赋存的地层条件,建立地质模型,进行有差分数值模拟,分析不同间距多煤层开采的沉陷特征,同时对比分析多煤层开采覆岩的位移量随间距变化的关系,揭示了不同间距多煤层开采覆岩破坏规律差异,为工程实践提供理论基础。Based on the layer conditions of the researched mining coal,the engineering geological model is generated for finite element numerical simulation to find out the subsidence feature of different spacing multi-seam mining,as well as comparative analysis the relationship of multi-seam mining displacement of overlying rock with distance change.The differences in overburden failure law of different spacing-coal mining is revealed,providing a theoretical basis for engineering Practice.
