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

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.
