摘　　要：基于大佛寺煤矿4上煤层作为4煤层的保护层进行开采的工程背景,为探索该特殊区域工作面诱冲规律,借助于现有的微震监测设备分析回采速度与微震“时间—空间—强度”特征参数之间的关系。结果表明:4上煤层作为4煤层的保护层开采可以有效降低工作面微震能量大小,该方案起到了较好的卸压作用;通过微震空间分布特征与回采速度的相关性,确定了合理的回采速度,为冲击地压防治体系设计提供了数据支撑。Based on the engineering background that the 4^(上)coal seam of Dafosi Coal Mine is used as the protective layer of 4 coal seam for mining,in order to explore the law of induced burst of working face in this special area,the relationship between mining speed and microseismic'time-space-strength'character⁃istic parameters is analyzed by means of existing microseismic monitoring equipment.The results show that the mining of the 4^(上)coal seam as the protective layer of the 4 coal seam can effectively reduce the micro⁃seismic energy of the working face,and the scheme has played a better pressure relief role.Through the cor⁃relation between microseismic spatial distribution characteristics and mining speed,the reasonable mining speed is determined,which provides data support for the design of rockburst prevention system.
