包头矿务局1956年开始建设,从1960年先后有五对矿井投产。五个生产矿均为超级瓦斯矿井,其中河滩沟、五当沟两个矿的瓦斯涌出量比较大,对安全生产的威胁严重,1960年五当沟矿发生瓦斯爆炸事故,1962年河滩沟矿因瓦斯大曾下马停建。因此,如何治服瓦斯是矿井移交后能否正常生产的关键。1965年在五当沟矿进行钻孔抽放上邻近层瓦 Baotou Mining Bureau started construction in 1956, from 1960, there have been five pairs of mines. Five production mines are super-gas mines. Among them, two gas mines, Hetan Gou and Wudanggou, emit large amounts of gas and threaten the safety of production. In 1960, a gas explosion occurred in Wudanggou Mine. In 1962, Due to large gas mine dismount stop construction. Therefore, how to cure gas is the key to the normal production after the mine is handed over. In 1965 in the Wudanggou drilling drainage adjacent to the roof tile
