摘　　要：针对店坪煤矿204综采工作面回采期间出现的上隅角瓦斯浓度较高,严重制约工作面安全生产问题,对上隅角瓦斯浓度较高产生的原因进行了梳理分析,针对性应用了采空区埋管抽采瓦斯、顶板裂隙带布置高位钻孔抽采瓦斯以及在上隅角安装使用风水引射器等瓦斯综合治理技术。应用结果表明,采用瓦斯综合治理技术后,204综采工作面上隅角瓦斯浓度稳定在0.5%以下,瓦斯治理效果明显。Shanxi Coking Coal Huozhou Coal and power group lulianshan coal and Power Co.,Ltd.fangshandianping coal mine 204 fully mechanized mining face during the mining period,the gas concentration in the upper corner is high,which seriously restricts the safety production of the working face.In order to solve this problem,the reasons for the high gas concentration in the upper corner of the fully-mechanized mining face are carefully analyzed.On this basis,the buried pipe drainage in the goaf After applying the above comprehensive gas control technology,the gas concentration in the upper corner of 204 fully-mechanized mining face has been stabilized below 0.5%,and obvious gas control effect has been achieved.
