摘要
分析了寺河矿二号井9号煤层"U"型通风系统综采工作面瓦斯涌出源,提出了邻近层顶板高位钻孔抽放、采空区埋管抽放、本煤层顺序抽放三种瓦斯综合治理方案,并阐述了各抽放技术的布置方式、技术参数、抽放效果。现场实用结果表明,采取上述瓦斯综合治理方案后,寺河矿二号井9号煤"U"型通风系统下综采工作面的上隅角瓦斯超限问题得到解决,确保了矿井的安全生产。
On the analysis of gas emission source of fully mechanized working face with U-typedventilation in seam 9, well 2 in Sihe Mine, the paper proposed three comprehensive control plans： gasdrainage with high-position drilling from adjacency seams, gas drainage with buried pipe in gob, and gasdrainage along seam. Besides, layout, parameters, and drainage effect of these three drainage technologies were presented.
