鹤庆县北衙外围矿区芹河矿段金铅多金属矿水工环地质分析研究

Study on Hydraulic Environment Geological Analysis of Gold Lead Polymetallic Ore in Qinhe Ore Block of Beiya Peripheral Mining Area,Heqing County

本文旨在讨论位于鹤庆县北衙的芹河矿段金铅多金属矿的水工环地质条件复杂性。该矿区存在含(隔)水层的分布,以及具有独特的水文地质特征、水力联系和地下水补径排条件。通过对该矿区水文地质特征、边界条件、充水方式等进行论述,本文预测了未来地下开采矿坑正常和最大涌水量,同时分析了矿区工程地质和环境地质条件。基于此,本文提出了矿山供水及防治水的初步建议,旨在为矿床开采提供详实的水工环地质资料。

The purpose of this paper is to discuss the complexity of the geological conditions of the hydraulic ring of the gold-lead polymetallic deposit in the Qinhe section of Beiya,Heqing County.There is a distribution of aquifer in the mining area,as well as unique hydrogeological characteristics,hydraulic connection and groundwater recharge and discharge conditions.By discussing the hydrogeological characteristics,boundary conditions and water filling mode of the mining area,this paper predicts the normal and maximum water inflow of the underground mining pit in the future,and analyzes the engineering geological and environmental geological conditions of the mining area.Based on this,this paper puts forward some preliminary suggestions on mine water supply and water prevention and control,in order to provide detailed geological data of hydraulic ring for deposit mining.
