Study on mechanical property and electromagnetic emission during the fracture process of combined coal-rock
The mechanical characteristics and electromagnetic emission rules during the uniaxial compression of the combined coal-rock were investigated in laboratory and its mechanical property was analyzed; the relation between mechanical characteristics and electromagnetic emission of the combined coal-rock was discussed. The results show that the combined coal-rock strength under the uniaxial compression is obviously different from that of single coal or rock and the fracture process of the combined coal-rock is gradual, accompanied by electromagnetic emission. This research has an important significance to further understanding of the mechanism and forecasting method of coal or rock dynamical disasters in theory and practice.
