茶洞矿区位于广东省西部，主要受吴川—四会深断裂带影响，矿区出露岩性主要以震旦系云母石英片岩为主。矿区地处亚热带，属南亚热带季风气候，区内雨量充沛，地下水和地表水补给、径流和排泄条件较简单，通过钻孔施工和水文地质检测等工作，对矿区供水水源做了初步评价，分析了矿区地表水动态和地下水类型及特征，初步探讨了大气降水及各类含水层对矿床充水的影响，判断本矿床水文地质条件简单，为矿区下一步工作提供了依据。
茶洞礦區位于廣東省西部，主要受吳川—四會深斷裂帶影響，礦區齣露巖性主要以震旦繫雲母石英片巖為主。礦區地處亞熱帶，屬南亞熱帶季風氣候，區內雨量充沛，地下水和地錶水補給、徑流和排洩條件較簡單，通過鑽孔施工和水文地質檢測等工作，對礦區供水水源做瞭初步評價，分析瞭礦區地錶水動態和地下水類型及特徵，初步探討瞭大氣降水及各類含水層對礦床充水的影響，判斷本礦床水文地質條件簡單，為礦區下一步工作提供瞭依據。

Chadong mining area,lying in western Guangdong,is mainly affected by Wuchuan-Sihui deep frac-ture belt with Sinian mica-quartz schist as outcrop lithology in this mining area.The area locates inside the subtropical zone which is characterized by south Asia tropical monsoon climate which is characterized by a-bundant rainfall.The conditions of supply,runoff and drainage of ground water and surface water are rela-tively simple.Through drilling exploration and hydrogeological test,the paper conducts an initial evaluation on water supply source of the mining area and an analysis of dynamics of surface water and types and features of ground water in the mining area,and initially elaborates on the effects of atmospheric precipitation and va-rious types of aquifers on deposit flooding,and thus concludes that the hydrogeological condition of the de-posit is simple and provides basis for future works in the mining area.
