The paste filling technique applied on solid waste of mines can solve the environmental problems caused by tailings and sewage. In China, tailings from metal mines occupy much land, break the ecological balance, pollute the environment, and even induce engineering geological calamity. For the paste filling tech, the concentration of tailings slurry can reach 74%-76% by weight after dewatered and thickened, the slurry is then mixed with water quenched slag and cement to form materials for paste filling, and transported to the underground goaf by pipeline in a form of plunger flow. Since the filling system´s construction in 2007, a mine in Yunnan has filled paste about 400,000 m³, handled tailings 440,000 tons and water quenched slag 80,000 tons, reclaimed sewage 1,000,000 tons. Therefore, the paste filling technique can not only fundamentally solve a series of safety and environmental problems by putting a large amount of tailings into the underground area, but also lessen the water pollution by improving the recovery rate of the waste water. To conclude, paste filling plays an important role in environment protection.
