摘　　要：曹家滩煤矿为新建矿井,针对曹家滩煤矿水质日均波动大,悬浮物不稳定,而且矿化度、有机物较低等特点,矿井水处理站采用絮凝斜管沉淀池、重力式无阀滤池和自动化超滤设备三段分级工艺将井下水分别处理为洗煤厂用水、地面生产消防用水、中水与井下消防洒水.矿井水经过分段、多级处理分别满足了不同回用阶段、不同生产工艺的水质需求,出水水质分别达到了《煤炭洗选工程设计规范》(GB 50359-2005)、《煤矿井下消防、洒水设计规范》(GB 50383-2006)水质标准,实现矿井水水资源的综合利用,实现了矿区与周边环境的协调发展.As a new mine,the water quality in Caojiatan Coal Mine fluctuates,with unstable suspended solids and low salinity and organic matters.The mine water treatment plant adopts a three-stage classification process,including flocculation inclined tube settling tank,gravity valveless filter,and automated ultra-filtration device,to treat water for different purposes,such as for coal washing plants,firefighting on the ground,and underground firefighting and sprinkler.After segmented and multi-stage treatment,the mine water meets the water quality requirements of different reuse stages and production processes.The effluent water quality has reached the water quality standard:“Coal Preparation Engineering Design Code”(GB 50359-2005)and“Firefighting and Watering in Coal Mine Design Code”(GB 50383-2006).The water treatment has realized the comprehensive utilization of mine water resources and the coordinated development of the mining area and the surrounding environment.
