突出煤层煤巷掘进工作面局部综合防突措施研究

Research on Local Outburst Prevention Measures for Working Faces of Roadway Excavation in Outburst Coal Seam

煤与瓦斯突出的防治是突出矿井开采中一项十分复杂的系统工程,依据“区域防突措施先行、局部防突措施补充”的原则,在实施区域综合防突措施经效果检验达标后,在采掘过程中仍必须执行局部综合防突措施,文章从工作面突出危险性预测、工作面防突措施、工作面措施效果检验、安全防护措施四个方面入手,对突出煤层煤巷掘进工作面局部综合防突措施进行了研究。

Coal and gas outburst prevention is a complicated system engineering for outburst coal mines.According to the principle of taking regional outburst prevention measures first and local outburst prevention measures as a supplement,local outburst prevention measures should be implemented during the excavation process even if the regional outburst prevention measures are implemented with the effect tested to be reached the standard.The paper studies the local outburst prevention measures for working face of roadway excavation in outburst coal seam from the aspects of outburst risk prediction,outburst prevention measures and prevention effect test in working face,and safety protection measures.
