9 Energy potential of thermal energy of mine drainage systems Utilization of groundwater heat at DTEK Pavlohradvuhillia mines Utilization of groundwater heat Hot water supply Heating of buildings and structures Mine water has enormous potential for heat production. In the Western Donbas alone, mines pump out about 30 million m3/year of groundwater, the temperature of which is +12...+18 °C throughout the year, which is quite enough for the efficient use of water-to-water heat pumps . In 2010, DTEK Pavlohradvuhillia's Blagodatna mine implemented a pilot project to introduce 800 kW heat pumps.
