摘要：
This paper is a review of research on the rock burst prediction by the electromagnetic radiation (EMR) technology and equipment. It is universally acknowledged that EMR signals are accompanying all stages of the deformation and fracture of rock or coal samples, so we can monitor the change of EMR signals to predict rock burst which is the result of the deformation and fracture of rocks or coals. Based on the EMR experiments of coal or rock, the effect and the generation mechanism of EMR signals are analyzed, the EMR monitors of KBD5 and KBD7 types are invented and applied in the rock burst prediction of coal mines in China. Similar to earthquake, there are obvious EMR precursors before rock burst in coal mines and EMR value increases suddenly or gradually, or with rapid EMR fluctuations. Besides, EMR can evaluate the effects of rock burst control measures as the destressing blasting and water injection. After these rock burst control measures, the EMR intensity value in the monitoring area decreases. In addition, EMR technology can be used to monitor the roof movement and forecast the periodic roof pressure on the working face which possibly causes rock burst. EMR technology is widely applied in some coal mines which have rock burst problems.
