摘　　要：冲击应力场、顶板关键层的运动和构造应力场的性质和分布状态是导致冲击地压发生的三个主要因素。该文分析了自重应力、地质构造、煤岩结构和覆岩运动与冲击地压的关系,综合考虑多因素的条件下划分了1306工作面冲击危险区,对工作面开采过程中冲击地压灾害的防治具有一定的指导作用。The stress field, the movement of the key layer of the roof, the nature and the distribution of the tectonic stress field are the three main factors that lead to the occurrence of rock burst. This paper analyzes the relationship between gravity stress, geological structure, coal and rock structure and the rockburst. The impact of danger zone of the 1306 working face is divided under the condition of multiple factors, which has a certain guiding role on the rockburst hazard prevention and control in the process of working face mining.
