针对典型煤矿岩样，研究了岩体在受压破坏时其电阻率的变化特征，详细介绍了有关试验过程，并设计了一种新的测量电路，从而大大提高了其观测精度． 通过对几十块岩样的测试分析，得出了几种不同类型的电阻率和压力变化关系曲线．通过试验说明了岩体电阻率是岩体破坏过程中变化十分敏感的参数，岩体电阻率法可以用来进行岩体动力破坏的预测、预报．
Aiming at the typical coal mine rock samples, the variation characteristics of the resistivity of the rock mass under pressure failure are studied. The relevant test process is introduced in detail. A new measuring circuit is designed to greatly improve the observation accuracy. Through the test analysis of dozens of rock samples, several different types of resistivity and pressure curves were obtained. The experiments show that the resistivity of rock mass is a very sensitive parameter in the process of rock mass destruction. The rock mass resistivity method can be used to predict and predict the rock mass dynamic damage.
