摘要
针对高瓦斯矿井选煤厂的煤仓瓦斯治理,采取在仓壁开自然通风孔和加装瓦斯集聚罩进行抽放的办法,既实现了瓦斯管理本质安全,又保证了正常的装车外运。
In the light of the gas control in the coal bunker of coal cleaning plant of highly gassy mine,this paper adopts the method of drilling natural air holes and adding the gas gathering covers on the wall of coal bunker for gas drainage,which not only realizes the essential safety of gas control but also guarantees the normal loading and outward transportation.
