MECHANISM AND TESTS OF MINE DISASTER PREDICTION BY RESISTIVITY METHOD

摘要: 岩爆和煤层突出灾害对煤矿的安全生产及生产效率有着十分严重的影响。本文讨论了电阻率法在矿山灾害预报中的应用,利用试验观测了岩样在破坏过程中电阻率的变化,其结果表明,岩石电阻率在其破坏过程中变化明显,说明电阻率法可以用于矿山灾害的预测、预报

Abstract: The rock burst and coal outburst have important influences on the mining safety,technology and production dfficiency in coal mine.The application of resistivity merthod in the mine disaster prediction is discussed in this paper,and the resistivity variation during the rock sample rupture is measured by the tests.The results show that the resistivity variation of rock is obvious during its rupture,and it suggests that the resistivity method could be used to predict the mine disaster.
