摘要(Abstract)：

为解决我国煤矿矿井水利用率低和排放污染环境等问题,促进矿井水的处理利用,论述了矿井水井下处理相关技术的基本原理、工艺路线、技术特点和工程案例,针对矿井水井下处理存在问题提出解决思路,并对矿井水井下处理发展前景进行展望。高密度沉淀、超磁分离和采空区过滤等技术能够实现悬浮物高效低成本脱除;成熟的膜处理和低温多效蒸发技术可广泛应用于矿井水浓缩脱盐;利用煤矿地下水库存储浓盐废水是实现矿井水处理废水零排放的一种有效方式。进一步开发适用于井下空间的高效化、模块化、可移动化的处理单元,增强处理单元的防爆性能、自动控制性能、安全监测性能,采用多种处理技术耦合,实现矿井水分级处理与分质利用,将是未来矿井水井下处理利用发展的必然趋势。
In order to solve the problems of low utilization rate of coal mine water and environmental pollution,and to promote the treatment and utilization of mine water,the basic principle,process route,technical characteristics and project cases of underground mine water treatment technology were discussed.Aimed at the question of underground mine water treatment,the solutions were put forward,and the prospect was prospected.The results show that high-density sedimentation,super-magnetic separation and goaf filtration technology can achieve high efficiency and low cost removal of suspended solids,the membrane treatment and low temperature multi-effect evaporation technology can be widely used in mine water desalination,the underground coal reservoir storing concentrated salt wastewater is an effective way to achieve zero discharge of mine water treatment wastewater. It will be the development tendency and direction of underground mine water treatment and utilization that includes to develop efficient,modular and mobile processing units for the underground space,to enhance explosion-proof performance of the processing unit,automatic control performance and safety monitoring performance,to achieve mine water treatment and quality classification with a variety of processing techniques.
