| 摘 要： | 为防止回采工作面冲击矿压对人员造成伤害，根据采空区硕板覆岩同心传播转移规律、近心多载规律及采空区周围煤岩体上的应力分布规律，确定了回采工作面冲击矿压的重点防范区域。实例证明：对于接续回采工作面，冲击矿压的重点防范区域位于工作面距离上出口20～30m内和距离工作面20～30m的上巷内。实例证明与理论分析结果吻合，该研究可为有效防治冲击矿压灾害提供参考。

| Abstract: | In order to prevent the rockburst from injuring staff on working face, this paper introduces the determination of the key prevention areas of rockburst on working face, according to the law governing concentric propagation metastasis, proximal overload, and stress distribution surrounding area of goal. The results show that the continuing working face should be provided with key prevention areas of rockburst, located 20 - 30 m from the top exit on working face and 20 -30 m from the working face in the top roadway. The example is consistent with the theoretical analysis. The study provides reference for the effective prevention and control of rockburst disasters. |
