摘　　要：为研究红阳三矿深部采区冲击危险程度,结合采区实际地质和生产条件分析并确定了冲击地压影响因素,把采深、上覆7#煤层遗留煤柱作为关键影响因素。采用综合指数法,对采区划分的网格进行冲击危险指数计算。根据计算结果,该采区地质影响因素综合指数为0.65属于中等冲击危险;开采条件影响因素中最大冲击指数为0.83,为强冲击危险;并对采区进行了冲击危险区域划分,其中受关键因素和火成岩墙影响区域为强冲击危险区域。To study the rock burst dangerous level in deep mining area of Hongyang No. 3 Coal Mine,the influence factors were analyzed and ascertained according to the actual geological and production conditions of the mining area. The mining depth and the remaining coal pillar of 7#overlying coal seam are regarded as the key influence factors. The impact hazard index of divided mesh in mining area was calculated with comprehensive index method. According to the calculation result,the comprehensive index of geological influence factors is 0. 65 indicating moderate impact risk,and the maximum impact index of influence factors of mining condition is 0. 83 indicating strong impact risk. The impact hazard areas of the mining area was divided,and the areas influenced by key factors and igneous rock wall were instrong impact risk.
