黄陇侏罗纪煤田冲击地压地质特征与防治

Geological Characteristic and Control of Rock Burst of Huanglong Jurassic Coal Mine Field

  • 摘要: 陕西省现有12对冲击地压矿井主要集中在黄陇侏罗纪煤田深部开采区,介绍了黄陇侏罗纪煤田冲击地压矿井地质开采条件与显现特征,结合黄陇侏罗纪煤田彬长矿区、永陇矿区各矿井煤岩层冲击倾向性鉴定、矿井、采区、采掘工作面冲击危险性评价以及防治冲击地压方案研究成果,总结分析了黄陇侏罗纪煤田冲击地压地质特征,彬长矿区、永陇矿区冲击地压发生主导因素为褶曲构造与厚硬顶板岩层。开展了建设矿井低应力优化布置,生产矿井及建设矿井的采掘工作面动静载荷源分源调控技术推广,并提出了下一步防冲建议,为黄陇侏罗纪煤田深部开发提供实践指导。

     

    Abstract: Most of the twelve rock burst coal mine of Shaanxi province located at Huanglong Jurassic coal mine field in deep,it illustrated its geological mining condition and characteristic,based on coal and rock bursting potential,bursting hazard evaluation of coal mine,mining area and working face and prevention and control method of rock burst of Binchang mining area of Huanglong Jurassic coal mine field and Yonglong mining area,and summarized rock bursting geological characteristic of Huanglong Jurassic coal mine field,the main induced factors of rock burst were fold and thick roof strata.And then low pressure optimal layout of coal mine was proceed,also promoted dynamic and static different stress source of working face,and some suggestions of rock burst control were also proposed,it could reference for mining in deep.
