摘 要:济宁二号煤矿93下07工作面采深大,轨顺受3上煤层与邻近的93下08工作面采空区双向支承压力影响,形成在高应力煤柱区内采掘活动,具有冲击地压危险。本文通过研究开采区域的煤岩冲击倾向、地应力值、开采深度、煤层顶底板性质、水的作用等冲击地压影响因素,应用综合指数法预测冲击地压危险,分析了发生冲击的应力条件、能量条件和扰动条件。综合预测93下07工作面轨顺冲击危险程度,制订了冲击地压防治方案,进行了大量的冲击地压危险检测及治理工程,实现了93下07工作面的安全生产。Jining II coal mine 93 under 07 face deep mining; rail along the seam by three adjacent 93 08 goaf under way bearing pressure, that pillar is formed in high stress areas extractive activities, with impact ground pressure hazard. This paper studies the impact of coal mining areas tend to stress values, mining depth, coal seam nature of the role of water burst factors, the application of comprehensive index method predict rockburst hazard analyzes the impact of stress conditions occur energy conditions and disturbance conditions. Integrated forecasting 93 under 07 face the impact of the degree of risk along the rail, developed rockburst prevention and treatment programs, a great deal of rockburst hazard detection and control projects, to achieve the 93 under 07 face safety in produetion.
