通过对黄岩汇煤矿煤层瓦斯赋存情况的分析，提出了掘进工作面、回采工作面、邻近层、上隅角和高抽巷等的综合瓦斯防治技术，并对抽采效果进行了分析。结果表明，实施该综合抽采方法后，掘进工作面煤层残存瓦斯量降为6．3 m3/t；回采工作面煤体残存瓦斯量降为4．287～6．315 m3/t，瓦斯压力降为0．04～0．12 MPa；回风巷瓦斯浓度平均降为0．26％，上隅角瓦斯浓度从未超限；有效地降低了煤层瓦斯压力和瓦斯含量，消除了煤与瓦斯突出危险性，保障了矿井的安全高效开采。

By analyzing the gas occurrence of coal seam in Huangyanhui coal mine,a comprehensive gas pre-vention and control technology,including heading face,working face,adjacent seams,upper corner and high pum-ping lane extractions,etc,are presented.The effects of gas drainage are analyzed.The results show that after the comprehensive extraction methods were implemented.The gas remainder quantity of tunneling face had declined to 6. 3 m3/t,the gas remainder quantity of working face had declined to 4.287 ~6.315 m3/t.The gas pressure had re-duced to 0.04~0.12 MPa.The average gas concentration of return airway had reduced to 0.26%.
