摘　　要：南屯煤矿的3_上、3_下煤层间距2～13 m,3上煤层开采中受巨厚红层初次断裂影响引发强矿震,并诱发采场形成冲击灾害,且在3_下煤层开采中仍发生强矿震。分析了开采3_下煤层上覆岩层的冒落和移动规律,得出3_下煤层采动引发矿震的机理。依据矿震诱发冲击机理,通过采取优化采面开采布局、减小采动对冲击危险区扰动和优化巷道支护体参数等措施,有效地保证了被解放层采场的作业安全,实现了安全开采。The distance between the upper No. 3 coal seam and lower No. 3 coal seam of Na- ntun Coal Mine was 2-13 m, strong mine earthquakes affected by the first breakage of extra thick red bed occurred in upper No. 3 coal seam, and the mine earthquakes caused rock burst disasters in working face, moreover, strong mine earthquakes also occurred in the mining of lower No. 3 coal seam. The caving and moving laws of overlying rock stratum in the mining of lower No. 3 coal seam were analysed, and the mechanism of mine earthquake triggered by the mining of lower No. 3 coal seam was worked out. On the basis of the mechanism, through optimizing mining ar- rangement and roadway support parameters and decreasing the disturbance of mining on rock burst danger area were adopted, which ensured safety in production of protective coal seam and realized safety mining.
