Beschreibung
Zusammenfassung:	A mine cooling power recovery system wherein 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 slurry sedimentation tank may be provided on the ground surface.
