摘　　要：为探明矿井水源特征及设计高效经济的排水系统,分析了裂隙水源特征及其关联因素,结果表明,矿井水源以岩溶裂隙水及构造裂隙水为主;控矿断层导水性在不同的构造深度不同,褶皱核部的劈理、裂隙易成为地表水下渗通道,而岩性对裂隙水的影响取决于岩石结构、矿物成分及裂隙导水性。优化后的5台泵3条管路并联分段排水系统符合安全与经济要求,实践证实新分段排水系统全年排水电耗比原有系统降低21.3%,吨水百米电耗降低23.6%,节约排水费用105万元/年。To investigate characteristics of groundwater source and design an effective and economical drainage system in mines,features and influential factors of fracture water source were analyzed.Results showed that groundwater sources were dominated by karst-fracture and structural fracture groundwater.The hydraulic conductivity of the ore controlled fault changed along with variable structural depths.Cleavages and cracks within the fold core tended to be galleries for groundwater.Influences of lithology on fracture water were depended on rock structure,mineral composition and hydraulic conductivity.The improved sublevel drainage system performed safely and economically,in which five pumps and three pipelines were connected.The yearly power consumption decreased by 21.3%compared with the original drainage system,and power consumption in 100 m per ton decreased by 23.6%,whereas drainage cost reduced by 1.05 million yuan per year.
