Abstract: The deep treatment and zero discharge of high salinity mine water is one of the serious problems faced by coal mining enterprises in the western region. Focusing on the high salinity mine water treatment project in Lingxin Coal Mine, this paper discusses in detail the "direct filtration system + reverse osmosis system" advanced treatment process and concentrated saline underground storage technology. Compared with the surface treatment system, the mine water underground treatment system not only achieves the goal of zero-liter sewage in the underground, but also significantly reduces investment and operation costs. At the same time, the use of goafs for underground storage of concentrated saline wastewater also provides a new path for zero discharge of mine water treatment.
