The principle of forecasting rockburst with the Electromagnetic Emission(EME) method is described.And EME was measured using KBD5 EME monitor in Sanhejian coal mine.The results show that forecsting rockburst with this method does not need drilling and takes less time and the accuracy is great.In addition,it can monitor the activity of coal or rock body in front of the face,so EME method is a promising one for forecasting rockburst.
