Study on moist-locking mining technique of cool water well coal mine

摘要

Cool water Wells coal mine is a modern large mine in Shaanxi Yulin-Shenmu coal mine areas. Coal mining had caused serious destruction and pollution to local geological environment and threatened the groundwater resources. If it couldn't control properly, the great accidents would be caused easily and even influence the development of mining cities later. Therefore, the paper puts forward some measures to protect groundwater resources and reasonable utilization of coal gangue, according to cool water well coal mine's environmental geological characteristics, which had important practical significance to mine construction and environmental protection.
