根据陈四楼煤矿井下灰岩水含水丰富、水压高的特点 ,在井下南北大巷内选择适当的位置施工两个钻孔 ,既起到了疏放水的作用 ,又满足了井下两翼生产用水的需要 ,同时还可以用于水文观测 ,具有较高的技术价值 ,取得了明显的经济效果。 According to the characteristic of rich water and high water pressure in the limestone of Chensilou coal mine, two boreholes are selected in proper positions in the north and south underground tunnels, which not only play the role of water diversion but also meet the needs of production water of the two wings , But also can be used for hydrological observations, with high technical value, and achieved significant economic results.
