摘要
为了更好、更有效地提高煤矿瓦斯治理工作,平岗煤矿采用了钻孔抽放、巷道抽放及采空区抽放等12种瓦斯综合治理方法,提高了瓦斯抽放的效果,大幅度地降低了工作面及回风风流中的瓦斯浓度。该瓦斯治理技术的应用,可有效地减少煤矿瓦斯事故,降低井下人员的伤亡,保障煤矿安全生产。
In order to improve coal mine gas control work more effectively, Pinggang mine uses 12 kinds of comprehensive management approach, like a drill drainage, roadway drainage and gas drainage etc. to improve the gas drainage effect, greatly reducing the face and the gas concentration in the return air flow. The application of the gas control technology can effectively reduce coal mine accidents, reduce casualties of underground personnel and protect coal mine production.
