Underground Mine Refrigeration Developments

Development and testing of an underground remote refrigeration plant D.J. STANTON Mining Services Consultant, Anglo Platinun The objective of this study was to develop, install, and test a small underground mobile refrigeration plant (MRP) to deal with some of the real problems associated with mine cooling in an operating mine.

The first use of artificial cooling for underground mines goes back to 1860s when heat control was done by transporting blocks of ice underground in ore cars. However, the earliest use of vapour compression refrigeration was in 1921 to cool an underground mine at a depth of about 2400 m at the Morro Velho mine in Brazil (McPherson 2012).

Underground mines of all sizes require a formal, planned ventilation system to deliver fresh air to all working places. Mine ventilation is the process of supplying sufficient fresh air to the U/G workings to achieve these purposes, ensuring proper distribution & use of the air, and controlling the return to surface of contaminated air.

Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on …

Ventilation in an underground mine is of critical importance to the occupational health and safety of underground employees. The atmosphere underground is limited and confined, and is thus readily reduced to a sub-standard (or even dangerous) condition if contaminants (e.g. gases, dusts, fumes) produced in the course of operations are not controlled, safely extracted or diluted to acceptable ...
