摘要
针对潞宁煤矿深部开采条件和地质构造情况,采用小孔径水压致裂地应力测量装置,对潞宁煤矿进行了井下地应力测试,结合测量数据,详细分析了其井下地应力的特征。使得巷道支护得到明显改善。
Lu Ning deep coal mining conditions and geological conditions were analyzed, the use of small diameter hydraulic fracturing stress measurement device for Lu Ning mines were underground stress tested, combined with the measured data, a detailed analysis of its underground stress characteristics was given which made the roadway significantly improved.
