| Abstract: | Electromagnetic emission(EME) effects during the deformation and fracture of coal or rock are studied by the experimental methods of uniaxal compression and different loading ways in this paper.The principle of forecasting coal and gas outburst by EME method is discussed and applied to forecasting the criticality of coal and gas outburst.The results show that the EME method is entirely feasible to forecasting the criticality of coal and gas outburst.It has many advantages,such as high accuracy,simple method,low work intension and cost,and indeed realizing non-contact space forecasting.The developing trend of coal and gas outburst forecasting theory is non-contact continuously dynamic space forecast. |
