摘　　要：岩溶地面塌陷、区域地下水位下降、采空区地面塌(沉)陷、矿坑突水等是广西矿山在开采过程中产生的最主要环境水文地质问题。从武宣盘龙铅锌矿矿区的地层岩性分布、地质构造条件、岩溶发育特征、水文地质特征、开采工程活动、矿坑疏干地下水影响等方面综合分析,揭示盘龙矿区存在的主要环境水文地质问题,并结合开采工程活动提出帷幕灌浆、回填灌浆加固、充填采空区、加强地面变形监测、先探水再掘进等防治措施与对策,为矿山有序开采及安全经济高效运行、矿床疏干排水方案及矿山深部开采设计提供科学依据。The collapse of karst ground,drop of regional water level,goaf ground collapse(sinking)of mining area,and mine water inrush are the main environmental hydrogeological problems in the mining process of Guangxi mines.This paper comprehensively analyzes the stratum lithology,geological structure,karst development characteristics,hydrogeological conditions,mining characteristics,drainage of underground water in Panlong mine area of Wuxuan.The result reveals that the main environmental hydrogeological problems in Panlong mining area are:karst ground subsidence,regional groundwater level drop,well springs dry up,subsidence and deformation of goafs,and ground fissures and water inrush from mines,etc.Prevention and control measures and countermeasures are put forward such as curtain grouting,backfill grouting reinforcement,filling goaf,strengthening ground deformation monitoring,exploring water first and then driving combined with mining engineering activities so as to provide scientific basis for orderly mining and safe,economic and efficient operation of the mine,drainage scheme of the deposit,and deep mining design.
