| 中文摘要: |
| 德兴斑岩型铜矿床为中国最大的露天开采矿床之一，为探究德兴铜矿床采区底部地下水的类型、来源和空间分布，从而为地下水防治和开采布局提供理论指导，本文对富家坞采区开展了水文地球化学和地球物理勘探研究。结果表明：在富家坞采区大气降水是矿区地下水的主要补给水源，地下水的水位与降水量关系密切，北东向的断层和裂隙（包括采动裂隙和节理）是控制地下水赋存情况的主要因素。根据上述充水特征，提出了“疏排-注浆-帷幕-截流”四位一体的防治水技术措施。本次研究显示，水文地球化学和物探勘探相结合，可揭示采区地下水的赋存状况和来源，并为制定相应的治理方案提供依据。 |
| 英文摘要: |
| The Dexing porphyry copper deposit is one of the largest open-pit mining deposits in China. In order to investigate the types， sources and spatial distribution of groundwater at the bottom of Dexing copper deposit， provide theoretical guidance for groundwater prevention and control as well as mining layout， hydrogeochemical and geophysical exploration studies were carried out in the Fujiawu mining area. Results show that atmospheric precipitation is the main source of groundwater replenishment in the Fujiawu mining area， and the groundwater level is closely related to precipitation. The northeast-trending faults and fractures （including mining-induced fractures and joints） are the main factors controlling the occurrence of groundwater in the area. According to the water filling characteristics of mining area， a set of measures called "draining-grouting-curtain wall-intercepting" are put forward for water prevention and control. This study demonstrates that the combination of hydrogeochemistry and geophysical exploration can provide a basis for understanding the occurrence and sources of groundwater in the mining area and formulating corresponding management plans. |
