摘要: 针对A 矿21406 工作面回采期间发生冲击地压危险问题,分析了21406 工作面冲击地压影响因素,包括开采
深度,褶曲、断层、冲刷带等形成的高静载应力,相邻采空区的高动载应力,冲击倾向性,采掘扰动等。通过采取具体
措施完善21406 工作面的冲击地压防治工作,预防冲击地压事故的发生。设计了21406 工作面回采期间水力压裂卸压方
案,以保证矿井安全生产。

Abstract: Aiming at the risk of rock burst during mining in 21406 working face of A Mine, the influencing factors of rock burst
in 21406 working face were analyzed, including mining depth, high static stress formed by fold, fault and scour zone, high
dynamic stress in adjacent goaf, bursting liability, mining disturbance, etc. Concrete measures were taken to improve the
prevention of rock burst in 21406 working face, prevent the occurrence of rock burst accidents. The hydraulic fracturing pressure
relief scheme during the stoping of 21406 working face was designed to ensure the safety of mine production.

Key words: mining face recovery; thick and hard roof; hydraulic fracturing; pressure relief scheme
