    STUDY ON DEFORMATION-FAILURE OF OVERBURDEN STRATA OF OVERLAPPING MINING

    • 摘要: 叠加开采煤层顶板覆岩破坏较单层开采复杂,为了掌握其发育规律,作者通过顶板工程地质特征结合井中测流、钻孔电视实测分析,利用离散单元法模拟煤层在叠加开采过程中顶板变形破坏,从而对顶板覆岩在采动过程中的离层裂隙空间分布等特征进行研究,总结出叠加开采覆岩变形破坏的规律,从而可以有效地指导叠加开采煤层顶板防治工作。

       

      Abstract: 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.
