定向千米钻机长距离探放采空区积水的应用

为了防止采空区积水浸泡煤柱和无轨胶轮车长期运行震动对煤柱的破坏,对胶轮车大巷以及整个四采区构成威胁,在不影响胶轮车大巷喷白亮化和无轨胶轮车通行等情况下,在四采区皮带巷采用定向千米钻机对二采区积水进行了长距离钻探疏放,最终成功钻探至采空区出水,并达到了预期的疏放水目的。

Application of Directional Kilometer Drilling Rig in Long-distance Detection and Drainage of Water in Goaf

In order to prevent the coal pillars soaked by water accumulated in the goaf and the longterm vibration of the trackless rubbertyred vehicles from destroying the coal pillars,which poses a threat to the rubbertyred roadways and the entire fourth mining area,the directional kilometer rig was used in the belt roadway of the fourth mining area to drill and drain the water in the second mining area for a long distance without affecting the whitening and brightening of the rubbertyred roadways and the passage of trackless rubbertyred vehicles.Finally the water in the goaf was discharged successfully,and the expected purpose of water drainage was achieved.
