摘　　要：山西省红旗煤矿8煤工作面自2014年以来多次发生冲击地压,为降低冲击地压频发引起的灾害事故,结合本矿实际情况分析了微震监测法、岩石噪声监测法、电磁辐射法和岩屑法4种冲击地压预测方法,采用煤层注水软化、大孔径钻孔卸压、顶板预裂爆破开展冲击地压防治工作,实施后工作面未发生冲击地压,达到预期目标。Since 2014,in the No.8 coal seam working face of Hongqi Coal Mine in Shanxi Province has experienced multiple rock burst accidents.In order to reduce the safety accidents caused by frequent rock burst accidents,four rock burst prediction methods,namely microseismic monitoring method,rock noise monitoring method,electromagnetic radiation method,and rock debris method,were analyzed.Coal seam water injection softening,large aperture drilling pressure relief method,and roof pre splitting blasting was used to carry out rock burst prevention and control work.After implementation,no rock burst occurred in the working face,achieving the expected goal.
