Comprehensive utilization system and technical innovation of coal mine water resources

In order to better guide the engineering practice of coal mine water treatment,guided by new concepts,such as “Two Mountains Theory”,“Life Community” and “Sixteen-character Principle of Water Control”,the paper summarizes four new modes of mine water resources utilization,namely,the use of quality water supply cascades,in-situ reuse of underground treatment,high quality water supply and zero emissions.The paper introduces the mine water resources and ecological utilization technology system,acid mine water treatment technology,mutual flushing filter,RO concentrated water utilization technology in TDS treatment process,and new technology of water resources utilization of mines,such as constructed wetlands and ecological ponds.It proposes the short-plate that the existing mine water treatment technology has inaccurate prediction of water inflow,underground high-efficiency processing equipment parameters and three research and development inadequate,and fewer feasible technologies in the field of mine water treatment with special pollutants.It is pointed out that water inflow must be considered from the development of accurate,effective,dynamic and comprehensive prediction methods.The underground high-efficiency treatment equipment should pay attention to the accumulation of basic data,such as relevant process equipment parameters,operating parameters and process control conditions,and strengthen the three research and development of mine water treatment equipment and the establishment of relevant standards.The mine water treatment with special pollutants should be well coordinated with the uniformity of commonality and individuality in time scales in different mines and different mining areas,strengthen research and application in related fields to form the best feasible technology.
