摘　　要：为了研究掘进工作面冲击地压危险性,以徐矿集团张双楼煤矿为研究背景,对74104工作面的3条掘进工作面进行微震,利用微震法研究了冲击地压危险性。研究表明,切眼掘进工作面超前影响范围为35~58 m,材料道西掘进工作面超前影响范围为18~76 m,材料道东掘进工作面超前影响范围为44~120 m;矿震强度受到掘进工作面与F1断层的距离影响,距离越近,矿震频次能量就越高。并针对此种情况提出了更为合理的巷道支护措施,保证了74104工作面的顺利安全掘进和回采。In order to study the risk of rockburst in the driving face,this paper takes Zhangshuanglou Coal Mine of xukuang group as the research background,studies the risk of rockburst in three driving faces of 74104 working face by using the microseismic method.The research shows that the leading influence range of the cutting driving face is 35~58 m,the leading influence range of the material Road West driving face is 18~76 m,and the material Road West driving face is 18~76 m The advance influence range of the driving face in the east of the road is 44~120 m;the mining earthquake intensity is affected by the distance between the driving face and the F1 fault,the closer the distance is,the higher the frequency energy of the mining earthquake is.In view of this situation,more reasonable supporting measures are put forward to ensure the smooth and safe driving of 74104 working face.
