Abstract:
Coal mine water usually contains a large amount of pollutants such as suspended particulates. Ultra-magnetic-separation technology was adopted to treat the coal mine water directly downhole. The treatment process, design parameters of main structures, operational effects and technical & economic analysis were introduced. The operation result showed that effluent quality of the system was better than Emission Standard for Pollutants from Coal Industry (GB 20426-2006), and the effluent could be recycled locally. The operation cost was about 0.21 yuan/m3. The annual operation cost was about 1.15 million yuan, and annual economic benefit was about 7.77 million yuan. It had realized the clean water into storage and clean water out of well, and played a positive role in promoting the energy conservation, consumption reduction and emission reduction of coal mining enterprises.
