摘要：
The Electromagnetic Emission(EME) is caused by the inhomogeneous variable speed and the deformation of various parts of the coal and the variable speeding movement of electrical particles during crack expansion. This article is about the EME rules before and after the coal sample failure in 4# coal seam of HuaFeng Mine by experiments. Deviation values methods to monitor and forecast the rock burst have been held. KBD5 apparatus has been used to monitor the 4# coal seam which has high danger of burst in HuaFeng Mine, many times of pressure rock were forecasted according to the EME rules.
