| 摘 要： | 基于煤（岩）体固有电阻率与煤（岩）体应力、应变的关系,以及影响岩石电阻率物理参数的因素,探讨了采场顶板岩体和煤层（体）在高压应力作用下,体积应变引起电阻率变化的过程和机械物理实质。分析研究了煤（岩）体电阻率观测技术监测由应力引起煤（岩）体失稳（突出或冒落）的技术路线的依据,提出了应用该技术路线的可行性及其主要研究方向。

| Abstract: | Based on the relation of natural resistivity with stress and strain of coal and rock mass, and the factors that affect the physical parameter of rock resistivity, the process and mechanically physical substance that bulk strain cause the change 01 resistivity of the rock mass and coal seam in roof under the high strain is discussed. The author analyzes the basis of destabilization( burst or breakage) that is caused by the stress. At the same time, the author also studies the observing technology of coal (rock) mass resistivity. Thus, the author proposes the feasibility and the main study direction of applying this technology. |
