小龙潭矿区为一山间盆地大型露天开采褐煤矿区。区内第四系、第三系、三叠系三个含水系统,就整体而言,它们的补给、径流、排泄自成体系,就局部而言,它们又有着一定的水力联系。 盆地基底及四周群山由三叠系地层组成,其岩溶裂隙水水压高,水量大,从坑底进入矿坑,直接威协矿坑开采。本文将以群孔抽水试验所获数据,利用地 Little Longtan mining area is a mountainous basin large open-pit mining brown coal mining area. The Quaternary, Tertiary and Triassic water systems in the region, on the whole, have their own supply, runoff and excretion system, and locally, they have some hydraulic connection. The basement of the basin and the surrounding mountains are composed of Triassic strata. The karst fissure water has high water pressure and large amount of water. It enters into the pit from the bottom of the pit and directly mines the mine. In this paper, the data obtained from the group hole pumping test, the use of land
