摘　　要：通过对干燥和湿润两种煤样单轴压缩过程中的电阻率测试实验,对比分析了两种煤样受载过程中的电阻率变化规律与电阻率变化原因,为利用电阻率法预测井下煤岩动力灾害,保障煤矿安全生产起到了一定的指导作用。In this paper, the resistivity of the dry and humid coal samples are tested in uniaxial compression and the change law of the resistivity of coal samples in compression are analyzed. The reasons of resistivity changing of the dry and humid coal samples are expatiated in detail. It would play a guiding role in accurately forecasting coal or rock dynamic disaster with resistivity method and protecting the production safety of the coal mine.
