摘要
文章主要介绍石港煤矿煤与瓦斯的共采技术以及山西焦煤集团的多分枝地面垂直井瓦斯抽采技术的原理与演进规律,对于提高我国煤矿井下瓦斯抽采率以及降低煤矿煤层瓦斯含量和井下瓦斯涌出含量,促进煤矿安全生产具有一定的借鉴意义。
The article mainly introduces the total stone harbor coal mine coal and gas mining technology more branch of Shanxi coking coal group,and the ground gas drainage vertical Wells introduces principle and evolution law of mining technology,to improve the coal mine gas extraction rate increasing and in a timely manner to reduce the coal mine gas content,in order to promote our country＆#39;s coal mine safety production has a certain reference significance.
