概述矿井岩层视电阻率实验的方法和内容,利用实验资料较详细地分析了岩石视电阻率的变化与其承受的应力一应变状态的关系,对于视电阻率的变化机制和方向性问题作了一定探讨。

EXPERIMENTAL STUDY ON THE VARIATIONS IN APPARENT RESISTIVITY ASSOCIATED WITH THE STRESS-STRAIN STATE OF THE ROCK-WALLS IN THE UNDERGROUND MINE TUNNELS

Experiments on the variations in apparent resistivity in the rock walls of the underground mine tunnels had been made for more them two years, meanwhile the stress-strain state of the walls was changing with adjoining tunnels being dug.This papev presents and analyses the obtained data in detail, which include those of stress, strain, apparent resistivity, and so on, The mechanism on variations of apparent resistivity and the problem about the directins of extreme values of the variations are discussed briefly.
