摘要
以李家庄矿2309综采工作面为例,结合现场实际情况分析了该工作面U型通风系统条件下瓦斯流动与涌出规律,实施了前进式埋管与走向高位钻孔联合抽采的上隅角采空区瓦斯综合治理措施。结果显示,该措施有效消除了高瓦斯矿井U型通风工作面上隅角瓦斯超限问题。
Taking 2309 fully-mechanized mining face in Lijiazhuang Mine for example,the gas emission law and governance principles were analysed combined with the actual situation under the U Type ventilation,the comprehensive gas control measure of go-ahead buried pipe and trend high drilling was put into practices to drain gas. The results show that,the comprehensive gas control measure has effectively eliminated the gas over limit problem at upper corner with U type ventilation system in high gas mine.
