【摘要】 瓦斯燃烧是煤矿开采过程中存在的重要危险因素之一,其发生是由多因素共同导致的灾害现象.结合平顶山十矿戊20160工作面的打钻情况,对影响钻孔瓦斯燃烧的危险因素进行了分析,根据分析结果建立了评价层次模型,运用层次分析法确定了影响钻孔瓦斯燃烧各危险性因素的权重系数,并对权重系数进行了层次总排序.计算结果表明:钻孔施工工艺、合理的配风量、煤层瓦斯含量等是防止钻孔瓦斯燃烧中优先考虑的影响因素,为煤矿防止及治理钻孔瓦斯燃烧提供了科学的理论依据.更多还原

【Abstract】 The main objective of present study is to analyze and evaluate factors affecting gas burning which occurred during drilling at Wu20160 working-face in No.10 coal mine of Pingdingshan.Based on analytical result,evaluation model on gas burning in drill hole is established by using analytic hierarchy process,weight coefficient of risky factors affecting gas burning is determined and hierarchy total taxis are made.The major factors affecting gas burning in drill hole such as working skills for drill hole,reasonable air,flux coal bed gas content and so on are determined as dominating one from the model,which can provide coal miner or technician with correct suggestion to prevent and control gas burning during drilling in coal mine.更多还原
