石门揭煤突出危险性预测及消突技术的研究

Forecast of Outburst Danger in Crosscut Exposing Coal and Research on Eliminating Outburst Technology

鹤岗矿业集团矿建公司承担施工的兴安煤矿四水平二分段机道石门采取"四位一体"综合防突措施揭穿22#,17#,18#突出煤层。在揭煤过程中,应用了工作面突出危险性预测方法、工作面钻孔排放防突措施、综合防突措施效果检验方法、安全防护措施等,安全地通过了三层突出煤层。

Mine Construction Company of Hegang Mining Industry Group Comp., constructs in 22^# , 17^# and 18^# coal bed at two segment of the fourth lever in Xingan Coal Mine, takes general measures as ＂four position and one body＂ to prevent the coal from outburst in order to expose the coal bed. During exposing coal bed, they use the way which forecasts coal bed outburst, and take the measures of drilling in working face to release the gas, and use the way of integrating all the measures to check up the effect, and all the other safety measures to get across three coal beds outburst safely.
