Research on in-situ purification technique of mine water in Shendong mining area

摘要

Coal mining can result in serious groundwater seeping and have negative influence on the vulnerable aquatic environment of Shendong mining area. It is necessary to exploit wastewater reuse technique that could lead to the positive evolution of desert. Based on the characteristics of the shallow-buried seam with thin bedrock and thick loose sand bed, the characteristics of the mine water quality and the goaf filling were analyzed. The in-situ purification technique of mine water was presented. Since the adoption of this technology, there have been some successful results in Shendong coal mining area, showing great theoretical and practical values to the green mining technology.
