摘　　要：文章对气相压裂技术在潞安矿区的高瓦斯难抽采煤层快速掘进、高瓦斯难抽采回采工作面高效抽采、回采工作面坚硬顶板弱化及高瓦斯、突出煤层卸压消突快速揭煤中的试验情况进行了总结,试验结果显示:气相压裂瓦斯综合治理技术工艺简单、可靠易行、安全、综合成本较低,可大幅度提高瓦斯抽采率和抽采速度,降低煤层瓦斯含量和瓦斯压力,在全国同类瓦斯地质条件的高瓦斯、突出矿井具有良好的推广前景。Gas geology of Lu＇an mining area,development of CO2 gas fracturing were briefly introduced. CO2 gas fracturing using in Lu＇an mining area were emphatically introduced,which include rapid excavation in high gas low permeability difficult extraction coal seam,high efficient gas extraction of working face,hard roof weakening in working face,pressure relief and outburst danger elimination and cutting through coal seam quick in outburst coal seam. The result of CO2 gas fracturing experiment in Lu＇an mining area showed that comprehensive gas control using CO2 gas fracturing can significantly improve gas extraction rate and extraction speed,reduce the coal seam gas content and gas pressure. So the technology of CO2 gas fracturing has a good promotion prospects in the coal mine with similar gas geological conditions in our country.
