摘要

By analyzing the characteristics and the production mechanism of rock burst that goes with abnormal gas emission in deep coal seams, the essential method of elimi-nating abnormal gas emission by eliminating the occurrence of rock burst or depressing the magnitude of rock burst was considered. The No.237 working face was selected as the typical working face contacting gas in deep mining; aimed at this working face, a sys-tem of rock burst prediction and control for coal seam contacting gas in deep mining was established. This system includes three parts: ① regional prediction of rock burst hazard before mining, ② local prediction of rock burst hazard during mining, and ③ rock burst control.
