摘要
以某深部矿井水压致裂应力测量资料为依据，分析了煤层底板岩体在矿山压力和原始地应力的联合作用下，在阻抗水能力方面的变化。探讨了隔水层带的阻水机理及构造破碎带易于突水的原因。分析了地应力、水压与裂缝扩展的关系。
Based on the measured stress results with hydraulic fracture method in a mine, the variation of waterresisting ability for floor rock mass under effecting of geostress and rock pressure is analysed and discussed. The waterresisting mechanism of impermeable layer and interferential zone which is easy for water inrush is discussed. The relations of geostress, pressures of confined water and crack propagation are analysed. The relations of initial geostress and seam floor water irruption are obtained.
