深井高地压沿空巷道围岩变形机理与支护技术研究

 分析了深井高地压沿空巷道的围岩变形机理，并以潘三煤矿两条沿空巷道典型试验为背景，采用数值计算方法确定了深井沿空巷道需留设的合理煤柱宽度为7~8m，进而提出了深井沿空巷道顶板及两帮应遵循的支护原则。现场工程试验结果表明，顶板以锚索桁架支护为主、锚杆支护为辅，两帮使用加长高强锚杆可以较好的解决深部矿井沿空巷道围岩大变形控制问题。

The Research of Surrounding Rock Deformation Mechanism and Support Technology about Gob-side Entry in Deep-mine High Pressure

The surrounding rock deformation mechanism of gob-site entry in deep-mine high pressure was analyzed. Based on the typical tests to the two gob-site entry in PanSan coal mine, and used numerical calculating method the rational coal-pillar width is seven to eight meters in the gob-site entry in deep-mine. The support principle of roof and both side of gob-site entry in deep-mine were proposed. The results of engineering test in site show that the anchor cable truss support was mainly responsible in proof support, and in additional to the cable support, meanwhile the lengthening high strength cable in both side support could be better solving the problem of the surrounding rock deformation control of gob-site entry in deep-mine.
