摘要
对3106孤岛工作面采用综合指数法来评价冲击地压危险性。在对3106孤岛工作面动静载扰动因素进行分析基础上建立冲击地压发生的断裂力学模型,对回采巷道支护体系防冲能力进行分析,为3106工作面冲击地压防治提出可行的安全技术措施,对该矿孤岛工作面安全高效生产具有重要意义。
The 3106 of island coal mining face of static and dynamic load disturbance factors are analyzed based on the fracture mechanics model of rockburst occurred and analyze the actual mining roadway system and scour in order to put forward feasible safety technical measures for 3106 working face pressure bump prevention and control. It is important for the isolated island working face safe and efficient production.
