摘　　要：不规则条带工作面往往存在冲击地压的可能,而冲击地压的破坏性极大,严重威胁煤矿安全生产。彭庄煤矿4307工作面属于不规则工作面,为保证安全回采,对四采区工作面的微震监测结果进行分析得出4307工作面冲击地压的主控因素为构造应力、断层构造及坚硬顶板,并论证主控因素的防控可行性,为工作面回采期间防冲工作的开展提供依据。Irregular strip working face always have the potential for impact ground pressure,which is extremely destructive and a serious threat to coal mine safety.The No.4307 working face of Pengzhuang Coal Mine belongs to the irregular working face.In order to ensure safe recovery,the microseismic monitoring results of the working face in the fourth mining area were analyzed,and it was found that the main controlling factors for impact ground pressure in the No.4307 working face were structural stress,fault structure,and hard roof.The feasibility of preventing and controlling the main controlling factors was demonstrated,providing a basis for the development of anti impact work during the mining period of the working face.
