摘　　要：采用水压致裂法对平煤股份一矿延主运输巷进行地应力测试,分析了矿区地应力的分布特征。测试结果表明:矿井深部已属高地应力区;矿区最大主应力为近水平方向,受构造应力控制;3个主应力与埋深呈近似线性增大关系。测量结果可为矿井巷道变形机理、支护理论研究和施工提供依据。The deep ground stress tests have been carried out by using hydraulic fracturing method in main transportation roadway of No. 1 coal mine of Pingdingshan coal industry. The distribution characteristics of ground stress in mining area are analyzed. Test results show that the ground stress level is high in this mine area, the maximum principal stress controlled by tectonic stress is nearly horizon- tal, the three principal stresses increases approximately linear with the increase of depth. The results can provide references for deform- ation mechanism, support theory and construction of roadway.
