| Mine water refers to the inflow of water to the underground mining space from coal mine. The water has been wasted, as well as the pollution of surrounding surface, ground water, and phreatic water in the mining area occurs when large amounts of mine water is discharged without taking any protective measures, ultimately destroying the mining environment. The study shows that the treated mine water with recycling technology can be reused as additional industrial production water in undergroung mining space, as well as production water, domestic water, and agricultural water supplies in order to solve the conflict of water resources, and help to protect groungwater. therefore, the recycling mine water would be the best chioce through the progess of sustainable development of mining industry and the solution to water shortage in mine area.Wu gou mine has finished underground purification system of mine water i n the water treatmentchamber440meters underground.the body of the system a dopts magnetic separation technology Through field investigation, material collec tion and sampling test and analysis, this study is expected to get the water qual ity of raw waterand that in the process of treantment, analyze the effect of the processand evalute on the water quality basede on thvarious funcyions. The stud y shows that:The quality of mine water purified by the managetic separation c an achieve requirements for quite a lot functions such as field irrigation, boiler, greening, ect. The quality of surplus released water also comply with secondar y level of integrated Wastewater Dischharge Standard.Meantime, by analyzing the economic benefits, it is regarded that the adoption of magnetic separation technology has advantages of saving the investment, sparing space and decreasing the cost, and the system also sets up successful model for resources of mine water. |
