摘　　要：采用多因数耦合评价方法分析巨厚砾岩下强冲击厚煤层工作面开采的应力环境,进行冲击危险区域划分,建立冲击地压危险性评价技术体系,对冲击危险区采取针对性的卸压措施;采用覆岩空间结构理论及数值模拟等手段,确定华丰煤矿1411工作面上下解放层的有效保护深度,通过提前开采上、下解放层,确保了强冲击厚煤层工作面的安全开采。The stress environment of thick conglomerate under strong impact of thick seam mining impact was analyzed by coupling method for evaluation of multi factor, hazardous impact system was classified, evaluation technology of burst risk of danger zone had been established, the measures of pressure unloading was put into effect. The 1411 working face of Huafeng Coal Mine under the effective protection of liberation layer depth was confirmed on study of the overlying strata spatial structure theory and numerical simulation method, the strong impact of thick coal seam working face was exploited safely.
