Method of cleaning of mine waters and restore the biological diversity of disturbed areas

Abstract

The aim of the work is to show the method of accelerated restoration of the degraded territory of industrial sites of liquidated mines with simultaneous purification of pumped mine waters. The paper proposes an improvement of the method of accelerated recovery of the degraded territory of industrial sites of abandoned mines with simultaneous purification of pumped mine waters through the use of an airlift unit that will allow to regulate the temperature of the water produced from the heat exchangers. The depth of placement of the airlift installation was determined by calculation. In order to maintain the temperature of the water in the bioplate system in winter at the level of 10–12 °C, mine water having a temperature of 34 °C must be supplied from the lower trunk of the airlift located at a depth of 800 m. To cool the water in the bioplato system to 25 °C in summer, the mine water with a temperature of about 13 C must be pumped out from the top of the shaft of the airlift to a depth of 120 m.
