【摘要】 钱家营煤矿地应力测量采用了空芯包体三维地应力计,测量获得了-600m水平两个构造区域的地应力数据,得出了该井田为水平应力占主导的构适应力场的结论,并分析了矿井巷道变形破坏方式与地应力的关系。更多还原

【Abstract】 The Type kx81 hollow inlusion Stress meter was applied in the Qiajiayeng mine that is a kind of three-dimensional earth stress measurement equipment. The earth stress data of two tectonic regions were achieved in -600m level.The conclusion was drawn that horizonal stress is predominant in tectonic stress field,which conforms with mine tunnel’s deformation and destruction.更多还原
