摘　　要：介绍了林西矿1021-2工作面瓦斯治理技术应用实践,在调整优化通风系统增加风量的基础上,通过采用尾巷卸放、上隅角预埋管和"2+1"高位钻孔交替联合抽放技术,对瓦斯治理效果进行了实际观测分析与检验研究,摸索出了适合林西矿12煤层赋存条件下综合瓦斯治理技术,取得了较好的效果。The application practice of gas control technology in Linxi Mine 1021-2 face was introduced. On the basis of adjusting and optimizing the ventilation system and increasing the air volume, the gas control effect was actually observed,analyzed and tested by adopting the technology of tailrace discharge, upper corner buried pipe and "2+1" high level drilling alternate joint pumping, and a comprehensive gas control technology suitable for Linxi Mine under the conditions of No. 12 coal seam was found, with good effect.
