摘要
通过对峰峰矿区薛村矿 92 71 2工作面矿山压力显现规律的研究 ,探明了大倾角“三软”煤层轻型支架放顶煤回采工艺在开采过程中矿山压力显现规律 ,为矿山支架选型。
Through researching the law of strata pressure behavior on 92712 coalface of Xuecun Mine in Fengfeng Mining District, this paper proves up the law of strata pressure behavior in the working course of light support caving technology in the steep inclined 'three soft' seam, and offers the basis of choosing the type of support and guaranteeing the safety to produce
