METHOD OF UTILIZING LOW-TEMPERATURE ENERGDY OF GEOTHERMAL HEAT FROM MINE WORKINGS AND SYSTEM THEREFOR

摘要

The invention solves the problem of the utilisation of low temperature energy of geothermic heat for heating accommodation and domestic water. The method according to the invention consists in that the geothermic low temperature energy, which is contained in the water, in the ground and in the filling material of the working chambers of non- operational and working mines, is removed via coils and is transferred to the heated spaces via a system consisting of pipes, a heat pump, an accumulator and a heat distribution, the water being used as medium in one part of the closed circuit and a salt-water solution in the other part. The system is characterised in that the coils (2) are arranged in the filling material or in the ground of the working chamber (1) and connected via pipes to the heat pump (3) and then to the heat accumulator (5), the heat pump (3), the heat accumulator (4) and the heat distribution preferably being arranged underground in non- operational mines, in particular in deep mines, and the heat pump (3) and the accumulator (4) being arranged preferably in the working chamber (1) and the heat distribution (5) on the earth's surface in working mines and in the working chambers of shallow mines.
