中文摘要：

深井冲击倾向采场的沿空巷道是冲击地压易发难防治区域。针对华丰煤矿埋深千米强冲击缺少了上保护层的开采条件，研究其沿空巷道防冲机制，将下工作面回风巷置于已采上区段运输巷底板下方卸压区域，实现了埋深超千米无区段煤柱开采；通过建立端头覆岩结构模型计算胶结顶板巷道支护强度，采用广义库仑理论计算采空侧压力评估两帮支护匹配性，确定的支护设计确保覆岩、两帮稳定；通过支架承载变形特征阐述其对冲击载荷的有效防冲机制。采用微震、地音、应力在线预警系统和钻屑法监测，实现区域预警一点监测量化验证预警，评价沿空巷道无冲击危险，不需要采取以往繁琐且难以保证解危效果的爆破、大直径钻孔卸压等工艺，且支护效果良好。研究成果对深井防治沿空巷道冲击地压有借鉴价值。

英文摘要：

Coal burst is hard to control and induced easily in gob-side entry. In order to eliminate coal burst risk for fully-mechanized face, lacking protection seam to release rock pressure, with strong coal burst proneness located in over 1 000 m depth in Huafeng coal mine, the return air way of next working face was settled just below transportation lane floor of the mined working face, and no section coal pillar mining was realized. Support strength was calculated with strata structure model, and lateral pressure of gob-side which was obtained by generalized coulomb theory have been taken into consideration for support design. Regional early warning was realized by microseismic monitoring（MS） and AE（sound monitoring）, while temporary warning was realized by on-line stress monitoring and drilling cuttings prediction. It shows that no coal burst risk existed in gob-side entry, So the previous blasting and large diameter pressure relief process could be eliminated. The research is of reference value for coal burst of gob-side entry prevention and control in deep coal mine.
