浅谈贺西煤矿深部区域瓦斯治理方案

Gas Treatment Plant for Deep Area of Hexi Coal Mine

根据井田基本资料并结合现场实际情况和测定的关键瓦斯参数,采用了开采底抽巷施工定向长距离钻孔及穿层钻孔进行预区域抽消突,最终实现矿井深部区域消突,抽采效果达标,为矿井的安全生产打下坚实基础。

This paper is based on basic data mining field and combined with the actual situation and the determination of key pa- rameters of gas, the exploitation of bottom drilling directional drilling and wear long alley pumping construction layer to advance regional smoke elimination, finally realizes the deep mine area, elimination effect of extraction, lay a solid foundation for mine safety production.
