| Abstract |
A modern ore mine, originally planned to excavate considerable quantities of minerals, closed down in the phase of preparations, for economic and other reasons. The two vertical shafts run down to a depth of 1200 m. They are located 1200 m away from each other, and each is 8 m in diameter. Two horizontal tunnels connect the two shafts, at 700 and 900 m depths. The warm water (52 ?C), pouring into the mine had to be continually drained out. When it was finally decoded to close down the mine, the pumps stopped and the warm water fully filled up the mine. The quantity of water is estimated at 300,000 m3. A major development project is going to take place at the Par?df?rdo Spa, only a few hundred meters from the mine. How would it be possible to make use of the heat of the water in the mine? |
