Mine cooling power recovery system |
| abstract |
A mine cooling power recovery system is disclosed. A low-pressure slurry pump for charging the mud slurry produced in a mine into a pressure changeover feed chamber is arranged in parallel to a warm water charging low-pressure pump and each of outlets of the two pumps has a changeover valve so that a single power recovery system pumps up both the mud slurry and a warm water out of the mine. A second embodiment of the present invention employs a slurry sedimentation tank provided on the ground surface. |
