摘　　要：为了核算井下磁分离水处理系统的节能量和经济效益,以3处不同水质特点的工程案例为研究对象,测量和验证了工程实施前后每吨矿井水提升百米的电耗指标变化,对比了工程投资、日常运行、设备维修和维护等方面的费用差异,分析了在矿井水减排、生产安全和社会责任等方面产生的间接经济效益。结果表明：井下磁分离净化水处理系统与地面水处理工艺相比,工程投资总额减少了约915.88元/t,日常运行费用减少了0.36~0.61元/t;工程实施后平均节电0.043~0.047 k Wh/（t·hm）,节能率9.39%~10.26%,节约主排水系统维修、维护费用0.19元/t。In order to improve the economic benefits and lower energy consumption of mine water underground magnetic separation system,three project cases with different water quality characteristics were chosen to test the changes of hectometer drainage electricity consumption per ton index before and after the project implementation.The investment,daily operation and equipment maintenance were compared.The indirect economic benefits brought by mine water emission reduction,production safety and social responsibility was analyzed.The results showed that,compared with the mine water surface treatment process,the total engineering investment and daily operation expenditure of mine water underground magnetic separation system was reduced about RMB 915.88 per ton and RMB 0.36 to 0. 61 per ton. After the project implementation,the energy-saving was 0.043 to 0.047 k Wh /（ t·hm）,the energy saving rate was 9.39% to 10.26%,the repair and maintenance cost savings of main drainage system was RMB 0.19 per ton.
