The issue of wastewater treatment in open-pit mining of mineral deposits is associated with great difficulties. Due to the constant tightening of requirements for the quality of discharged wastewater, its treatment in the sedimentation reservoirs and clarification ponds does not ensure the achievement of MPC values; in addition, these treatment facilities occupy significant areas of land. It should also be noted that the open-pit mines, as a rule, have several water outlets remote from each other, besides changing their location as the development of mining operations proceeds. For example, OJSC "UK "Kuzbassrazrezugol" has more than 30 places of water use, taking into account that the company structure includes 7 open-pit mines. In the article some results of analyses of pit waste water before and after its treatment in artificial filtering massifs at the mining enterprises of Kuzbass are presented. Preliminary dependences of changes in pollutant impurities in quarry water on different composition of coal waste have been established.
