Monitoring and Measuring of Mine Pressure Bumping and Prevention and Control Technology in Huating Mine

  • 摘要: 为有效防治华亭煤矿冲击地压,系统分析了矿井冲击地压发生的原因,建立了以微震法为主,声发射、电磁辐射及钻屑检测为辅的冲击地压综合监测和预警管理体系。通过优化工作面布置、煤柱宽度、采放比、推进速度,改善了开采技术条件。采用煤层注水、顶底板深孔爆破、煤体卸压爆破及大直径钻孔等措施,实施主动解危。同时加强巷道支护和个体防护等强化防范措施,使冲击地压对矿井生产的影响时间由每年36 d减少到6 d,保证矿井安全生产。

     

    Abstract: In order effectively prevent and contral the mine pressure bumping occurred in Huating Mine, the cause of the mine pressure bumping occurred was syst ematically analyzed and a mine pressure comprehensive monitoring and measuring and early warning management system was established mainly with micro seismic method and secondary with the acoustic emission, electromagnetic radiation and drilling cuttings detection.With the optimization of the coal mining face layout, coal pill ar width, mining and caving ratio and the coal mining face advancing rate, the coal mining technology condition was improved.With the application of the seam water inj ection, the deep borehole blasting in the roof and floor, pressure releasing blasting in seam, the large diameter borehole and other measures, the mine pressure bumpin g danger could be actively released.Meanwhile the mine roadway support was enhanced and the personnel protection and other enhanced prevention measures conduc ted, the time of the mine pressure bumping affected to the mine production was reduced from 36 days to 6 days per year.The mine safety production could be ensured.
