高位裂隙抽放与纵向导风障技术相结合控制回风隅角瓦斯新应用

Wind Barrier Technology in Controlling Corner Gas in Return Air

煤层群瓦斯治理最有效的手段要靠抽采达标,常用的抽采方法有:本煤层抽放、采空区抽放、高位钻孔抽放、专用瓦斯巷抽放等.文章结合山西蒲县宏源集团郭家山煤业有限公司2201工作面回风隅角采用高位裂隙抽放技术和搭设纵向导风障技术的应用,对煤层群控制瓦斯提出了新的方法.并通过30天的不间断实际测试记录,对这种方法处理回风隅角瓦斯积聚的可行性和有效性进行了检验,并进行了实际应用,得到了良好的效果.

The most effective means of gas control in coal seam group is to rely on gas drainage, including： gas drainage from coal, gas drainage in goaf, high drilling drainage, drilling at special gas road and so on, which can improve the safety of coal mining in working face and achieve significant benefits. Based on the high fracture drainage technology and the application of the erection of the longitudinal ventilation technology on the corners of 2 201 working plane in Guojiashan Coal Company of Hongyuan Coal Enterprise in Pu county, Shanxi , the article puts forward a new method about the group control in coal seam group. Through continuously actual test records for 30 days, the feasibility and validity of this method on the application of dealing with the gas accumulation at the upper corner are tested. And the methods are put into long-term use, which provide an economic and practical technology for the governance of gas accumulation on working face.
