摘　　要：永安煤矿3426掘进工作面埋深超过900 m,掘进过程中经过永安向斜,同时揭断层F21,在构造区域有发生冲击地压的可能。简要分析了诱发掘进工作面冲击地压的原因,阐述了冲击地压的诱发机理,有针对性地提出了相应的防止冲击的安全措施,有效保障了该区域的安全开采。对掘进头构造区煤层冲击危险性的分析,为下一步高复杂应力条件下煤层巷道工作的开展有一定的指导意义。The 3426 driving face of Yongan Coal Mine has a buried depth of more than 900 m.In the process of driving,it passed through the Yongan syncline,and the fault F21 was exposed at the same time,so there was a possibility of rockburst in the structural area.This paper briefly analyzed the causes that induce the rock burst in the driving face,expounded the induced mechanism of the rock burst,put forward the corresponding safety measures to prevent the impact,and effectively guaranteed the safe mining in this area.The analysis of the coal seam impact risk in the structural area of the heading end has certain guiding significance for the next work of the coal seam roadway under the condition of high and complex stress.
