吉林省复兴村金矿区水文地质特征及涌水量预测

摘要

Fuxingcun Gold Deposit is a small medium-low temperature hydrothermal gold deposit related to the magmatic activities in late Yanshanian period discovered in southeastern Jilin Province in recent years. The main wa-ter-filled aquifer of the deposit is karst fractured marble aquifer of Zhenzhumen formation of Laoling group complex. The water yield is low to medium class,permeability and groundwater recharge conditions are poor,Quaternary cover thin and hydrogeological boundary simple,making a deposit with simple hydrogeological conditions. This paper predicts the water yield of No. 3 ore body by means of "coefficient of infiltration from precipitation method" and "big well method" and poses recommendation of water drainage to provide the basis for mining construction and development.%复兴村金矿床是近年在吉林省东南部发现的一个小型的与燕山晚期岩浆活动有关的中低温热液金矿床. 矿区主要充水含水层为老岭岩群珍珠门组大理岩岩溶裂隙含水层,富水性为弱—中等富水,渗透性差,地下水补给条件较差,第四系覆盖层薄,水文地质边界简单,属水文地质条件简单的矿床. 采用"降水入渗系数法"和"大井法"对3号矿体矿坑涌水量进行了预测并提出排水建议,为后续的矿山开采技术条件提供必要的依据.
