MECHANISM AND TESTS OF MINE DISASTER PREDICTION BY RESISTIVITY METHOD

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.
