屯兰矿12407综采工作面瓦斯抽采研究

Study on Gas Drainage in 12407 Fully Mechanized Face of Tunlan Mine

屯兰矿12407工作面位于南四盘区,该工作面采用一次采全高综合机械化采煤,瓦斯钻孔采用本煤层顺层钻孔、高低位邻近层钻孔、顶板走向长钻孔、上隅角悬管、横贯埋管抽采上隅角瓦斯。本工作面的试采成功,给此类工作面钻孔选型及瓦斯治理提供了经验借鉴。

The 12407 working face of Tunlan Coal Mine is located in the south fourth panel area.The working face adopts one-time full height comprehensive mechanized coal mining.The gas drilling adopts the drilling along the seam,the drilling near the high and low position,the long drilling along the roof strike,the hanging pipe at the upper corner,and the cross buried pipe to extract the gas at the upper corner.The successful trial mining of this working face provides experience for the selection of borehole and gas control in this kind of working face.
