Sicomines铜矿是世界级特大型铜矿,是在前人开采18年停产15年后重新扩大规模开发的矿山,矿区为加丹加矿脉的一部分,区域地层主要为罗安群和孔德龙古群,罗安群及其矿脉中白云石和白云质砂岩交替出现,地层、水文地质条件导致背斜向斜地层深度破碎,含水层厚度大,富水性透水性强。在详细分析矿区水文地质条件的基础上,从水文地质条件及经济技术合理性出发,确定矿坑水必须预先疏干,首先采取地表井疏干,然后采用巷道和垂直放水孔联合疏干的方案,并提出了一系列矿山防治措施,该方法在同类地区具有推广价值。
The Sicomines copper mine is a world-class super-large copper mine. It was exploited for 18 years and was re-expanded after 18 years of mining. The mine is a part of Katanga veins. The main strata of the area are the Loan and Conde Dragons, In the veins, dolomite and dolomitic sandstones alternately appear. The strata and hydrogeological conditions lead to the deep crustal anticline anticlinal formation, the thick aquifer and the strong water-permeability. Based on the detailed analysis of the hydrogeological conditions in the mining area and starting from the hydrogeological conditions and economic and technological rationality, it is necessary to make sure that the mine water has to be preliminarily dewatered. Firstly, the surface wells should be dredged, then the plan of tunneling and vertical drainage holes should be combined and dredged. And put forward a series of mine prevention and control measures. The method has the promotion value in similar areas.
