| Abstract: | The principle of monitoring rock burst with the Electromagnetic Emission(EME) method is described.According to measured results,the critical value of the intensity and pulse number of EME when the danger of rock burst could occur is determined,and a variety law of EME is obtained.The results show that monitoring rock burst with this method is feasible and takes a short time,the accuracy of forecasted results is great.In addition,EME method can monitor the behaviour of rock mass in front of the face.So,EME method is a promising one for monitoring rock burst. |
