安徽省凤阳县江山-大王府金铅锌矿矿坑涌水量预测

Prediction of Water Inflow in the Jiangshan Dawangfu Gold Lead Zinc Mine Pit in Fengyang County, Anhui Province

本文以安徽省凤阳县江山-大王府金铅锌矿为例详细介绍了矿区概况、矿体特征、水文地质条件、并运用大井法、廊道法两种方法对矿坑涌水量进行预测计算,明确了方法的选择、适用条件等。通过两种方法预测计算对比,分析了误差原因。对以后实际工作中计算矿坑涌水量起到一定的参考作用。

This article takes the Jiangshan Dawangfu Gold Lead Zinc Mine in Fengyang County,Anhui Province as an example to provide a detailed introduction to the mining area overview,ore body characteristics,hydrogeological conditions,and the use of two methods,namely the large well method and corridor method,to predict and calculate the water inflow of the mine pit.The selection of methods and applicable conditions are clarified.By comparing the prediction calculations using two methods,the reasons for the errors were analyzed.This can serve as a reference for calculating the water inflow of mining pits in future practical work.
