ABSTRACT:
For cooling of underground mine-shafts which extend over several levels at different depths and/or of the machinery installed therein, a tube-chamber feeder system which is operated for the hydraulic transport of solids is used. With this arrangement, the cooling liquid is supplied to the feeder system and to the high-pressure side of the tube chambers from above ground level through a high-pressure circulation of the cooling liquid and subsequently the cooling liquid from the tube chambers is forced through a low-pressure liquid circulation for transfer to the equipment requiring cooling. The essential requirement here is that the cold water which serves as the cooling liquid should be first of all fed from the feeder system into the tube-chambers which are located on the different levels of the mine-shaft respectively, following which each of these tube-chambers should be supplied separately, if the occasion demands, with hot-, or re-cycled-, water obtained from the equipment which required cooling, from their own low-pressure liquid circulation, for the purpose of expelling the cooling liquid towards the mining equipment requiring cooling.
