摘要
随着开采深度的加大,高瓦斯矿井采煤工作面瓦斯涌出量会越来越大,鹤煤集团三矿开展了高位瓦斯抽放巷治理瓦斯技术研究,配套大管径抽采,解决了单一低透煤层瓦斯超限问题,实现了综放工作面的高产高效生产。
With the increasing of mining depth, the gas emission in coal face of high - gas mine will become increasingly. Hebi coal group carries out the study of gas control technology of high level gas drainage tunnel. Matching with large diameter drainaging, the gas gauge problem in single low permeability coal seam is solved, and the high yield and efficient production in fully mechanized caving face is achieved too.
