摘要
论述了张集矿北区17278工作面瓦斯综合治理的必要性。通过对17278工作面瓦斯地质情况分析,利用移动抽采泵和地面永久瓦斯抽采泵采用老塘埋管抽采、高位钻孔抽采、回风巷边孔抽采和高位抽采巷道抽采、工作面煤层注水等瓦斯综合治理手段,对17278工作面进行瓦斯抽采,同时加强了对工作面上、下隅角的瓦斯管理,确保了该面的安全顺利回采,实现了高产高效。
The necessity of gas comprehensive management of the 17278 face, north district, Zhangji Coal Mine is discussed. The gas comprehensive management measures are adopted for the 17278 face gas drainage, such as draindge of using the moving pump and ground permanet pump burying pipes at the old roadway, drainage of drilling holes at the high position, drainege at the side holes of the back wind roadway and high position roadways, the face water flooding of the coal seam. At the same time, the gas management to the up and down corner of the face is strengthened. The safe and smoth mining is ensured. The high production and effiency are realized.
