摘　　要：分析了铜陵冬瓜山铜矿床60~#线以北深部水文地质特征,并探讨了防治水措施。研究表明:(1)坑道结构面以节理裂隙和层面为主,坑道突水的水化学类型以HCO_3·SO_4-Ca型为主,属于较典型的沉积岩地区溶滤水,主要离子以碳酸钙溶解及碳酸钙与白云岩共同溶解为主;(2)矿床深部初步确认的导水构造有8条,其中F_(15)、F_3等2组构造因富水性中等—强、突水危害性大被视为重点关注构造;(3)总体上矿床深部的含水层以构造裂隙导水为主,其中矿体南东段水文地质条件简单,北西段水文地质条件较复杂;(4)矿床60~#线以北的防治水重点区域为矿体北西段,今后在该区域进行探采工作时须进行超前探水,对于重点关注的构造应按照"有疑必探、遇水即注"的原则进行治理。The hydrogeological characteristics of the deep of the north of 60~# line of Dongguashan Copper Deposit is analyzed,and some related countermeasures of water prevention and controlling is proposed. The study results show that：（1）structural plane of the tunnel is dominated by joint fissures and layers,the hydrochemical type of water inrush in the tunnel is mainly for HCO3·SO4-Ca,which belongs to the typical dissolving water in sedimentary rocks region,the major ions may be derived from the dissolution of calcium carbonate and the dissolution of calcium carbonate and dolomite;（2）8 water guide structures have been preliminarily confirmed in the deep part of the deposit,among them,F15 and F3 structures are characterized by water-rich medium-strong and water-inrush hazards,so,they are regarded as the important ones that should be studied emphatically;（3）in general,aquifer in the deep of the deposit is dominated by structural fissures,the hydrogeological conditions of the southeast of the ore-body is simple,while the hydrogeological conditions of the northwest of the ore-body is complex;（4）the important area of water prevention and controlling of the north of 60~# line is the northwest of ore-body,when the further prospecting work and mining work are done in the area,some related advanced water exploration work should be conducted,the above important structures should be processed based on the principal of ＂ if the anomaly phenomenon is existed,some related advanced water exploration work should be done＂ and ＂ if the waterinrush phenomen is existed,grouting water plugging measures should be taken＂.
