Shallow Thick Coal Seam Rockburst Of Working Face Of Type W Behavior

Kuan Gou coal mine E1148 mining coal seam is thick coal seam, W type layout, after inspection, the exploitation of coal seam has strong rock burst tendency, the roof has a weak impact orientation, and mining is the rockburst risk.Based on the E1148 working face as the research object, the use of micro system, monitoring system and monitoring method, A comprehensive analysis of research methods through theoretical analysis, monitoring analysis and field application of combining, The main content of the E1148 working face roof first weighting, the periodic weighting, the systematic research on preventing measures-then geting the basic rule of pressure in the E1148 working face of mine.With the development of prevention and control scheme of the monitoring results, the large diameter deep hole blasting, coal roof pressure relief blasting controlling measures can effectively reduce the impact of dangerous area. In the prevention and control measures after the implementation of strong mining earthquake activity, reduce stress, and drilling cuttings weight decreased, reduce the energy of microseismic events should be near the surface, so that the pressure relief technology, the development of the mine pressure bumping danger governance plays a significant role in.The results of this study provide a guarantee for the safety of coal mining working face. At the same time the research of shallow coal seam roof is hard to run under the conditions of coal mining safety is of great reference significance.
