摘　　要：安庆铜矿于1991年投料试车,1999年延伸至-580 m水平开采,2014年延伸至-900 m水平开采。矿山自2000年以来,年处理量一直稳定在115.5万t,延伸开采后,矿山设计矿石综合电耗约为90(kW·h)/t。为进一步降低能源消耗,对矿山供配电系统、压风系统、通风系统、提升系统、选矿系统、给排水系统、选矿系统等进行优化与改造。到2020年,矿山综合电耗为68(kW·h)/t,取得了明显效益。The Anqing Copper Mine was put into trial operation in 1991,extended to-580 m level mining in 1999,and extended to-900 m level mining in 2014.Since 2000,the mine's annual processing capacity has been stable at 1.155 million tons.After extended mining,the mine's designed comprehensive power consumption for ore is about 90(kW•h)/t.In order to further reduce energy consumption,the mine's power supply and distribution system,compressed air system,ventilation system,lifting system,beneficia⁃tion system,water supply and drainage system,beneficiation system,etc.have been optimized and trans⁃formed.By 2020,the comprehensive power consumption of the mine will be 68(kW·h)/t,which has achieved significant benefits.
