南泥湖露天矿区采场水力联系及矿坑涌水量预测

为了查明南泥湖露天矿区采场范围内水力联系及矿坑涌水量，分析了含水层类型及其富水性特征，地下水补给、径流、排泄条件，地下水的基本特征等，基于此，采用长期水文监测、示踪试验及水化学分析等方法，研究了大气降水、地表水、地下水及矿坑涌水之间的水力联系及相互转换关系；并分析了露采矿坑的涌水因素以及预测了露采矿坑涌水量，主要包括矿坑大气降水补给量、地表径流量和地下水补给量。研究为后期水文地质监测以及地质灾害防治提供了技术支持。

Hydraulic connection of stope in Nannihu open-pit mine area and prediction of mine discharge

In order to find out the hydraulic connection and the mine discharge in the open-pit mining area，the types of aquifers and their water-rich characteristics，groundwater recharge，runoff，drainage conditions，and basic characteristics of groundwater were analyzed.Based on this，long-term hydrological monitoring，tracer test，hydrochemical analysis and other methods were adopted to study the hydraulic connection and mutual conversion between atmospheric precipitation，surface water，groundwater and mine water inrush.The water inflow factors of the open pit were analyzed and the water inflow of the open pit was predicted.It mainly includes the mine pit atmospheric precipitation supplement，surface runoff and groundwater supplement.The study provides technical support for the later hydrogeological monitoring and geological disaster prevention.
