Problems of using mine water in technological processes of coal mining enterprises to reduce impact on the environment
Annotation: The article considers the environmental problem of mine waters in coal mining regions, which has remained relevant for many years. Mine waters are formed due to underground and surface waters penetrating into mine workings. From 3 to 10 m3 of mine waters per ton of mined coal enters the hydrological network. The constant transition of mining operations to deeper horizons and the complication of hydrogeological conditions lead to a further increase in the volume and pollution of associated pumped waters with various substances, as well as the depletion of underground aquifers, including those saturated with clean drinking water. In the process of coal mining, large volumes of mine waters are formed in the Donetsk region, which is more than 300 million m3 / year, and scientifi c research and developments in the fi eld of rational use of water resources: the use of mine water as an alternative source of water supply, due to an acute shortage of fresh water; the development of new and improvement of existing methods for cleaning mine water from pollutants, in particular suspended matter and mineral salts; modernization of treatment facilities and the introduction of new and eff ective technologies. A method for using purifi ed mine water for the technological needs of vacuum pumping stations is proposed. A plan for the implementation of research to improve the method of softening mine water for vacuum pumping units is drawn up.
Keywords: mine water, pollution, cleaning schemes, reuse, recirculation cycles, vacuum pumping stations, carbonate waste.
