摘　　要：通过对义煤集团千秋煤矿有冲击倾向巨厚煤层冲击现象现状、特点及影响因素分析,结合该矿的生产实践,提出了适合该条件的冲击危险预测方法及相应解危措施,并进一步提出解危措施效果检验方法以及以上工作失败、冲击地压突发情况下的应急措施;在此基础上建立了适合义煤千秋矿巨厚煤层冲击地压防治的安全开采体系,成功地进行了巨厚煤层的综放开采,从而为有冲击倾向巨厚煤层的安全开采提供了成功范例.Based on the study of extremely thick coal seam with coal bumping tendency in Qianqiu coal mine, characters and influence factors of coal bumping are recognized. Suitable forecasting measures, preventing measures, examining methods for preventing measures, and effectiveness and crashing measures that can be put into effect once above measures all failed are put forward. The safety system of extremely thick coal seam is built and the extremely thick coal seam with coal bumping tendency in Qianqiu coal mine is extracted smoothly with fully mechanized sub - level caving mining technology. It can be the successful example for extracting extremely thick coal seam with coal bumping tendency.
