摘要
吉林省桦甸市八道河子钼矿区地质构造发育,地下水丰富,赋水条件复杂。I号矿体南段现开采标高270 m,已在侵蚀基准面以下140 m,矿体最低控制标高200 m,在侵蚀基准面以下210 m;I号矿体北段现开采标高305m,已在侵蚀基准面以下105 m,控制矿体最低标高260 m,在侵蚀基准面以下150 m。随着矿山采矿的继续,采掘位置将不断加深,巷道内涌水量不断增多,排水量不断加大。在今后的生产过程中,水文地质问题将越来越突出,因此,对吉林省桦甸市八道河子钼矿的水文地质条件进行分析研究,提出有效的排水措施,将对矿山今后的生产安全具有一定的指导作用。
There are the geological structure development, abundant groundwater and water bearing condition complex in Badaohezi molybdenum deposit of Huadian City, Jilin Province. No. I orebody in the Southern mining elevation is 270 m,it have been in below the base-level of erosion of 140 m, the lowest control elevation of ore body is 200 m, which is 210 m below the base-level of erosion, No. I orebody in the nohern mining elevation is 305 m,it have been in below the base-level of erosion of 150 m, the lowest control elevation of ore body is 260 m, which is 150 m below the base-level of erosion.Mining location will continue to deepen, increasing the outflow of water in the tunnel, increasing the water displacement with the continuation of mining. The hydrogeological problems will become more and more prominent in the future production process, Therefore, the hydrogeological conditions of Badaohezi molybdenum mine of Huadian city of Jilin province are analysized,the effective drainage measures is proposed.which will have certain guiding function to the production safety of the mine in the future.
