- Abstract
- Stawell Gold Mines (SGM) is an underground mine is operating 1350 m below the surface. Underground cooling systems have been installed to supplement the ventilation system and to cool the mine to acceptable working levels. Previously, SGM relied on AustCold bulk air cooling units to cool the mine. However, these units were not designed to meet the demands of the hotter conditions as the mine got below the 1200 m level. SGM has installed three new cooling units from Caterpilla (CAT). Two of the units were already in operation at the start of the study and the third was due to be in use within a few months. This study aimed to continously monitor the cooling performance of these new chiller units and compare the against the old AustCold units. The performance of the three units was also compared amongst themselves to ensure that they provide consistent results throughout the mine, regardless of their location. These results will be monitored over a long period to also ensure consistency with time. In comparing the two types of units, the factors that actually affect the performance of the chiller units when subject to various conditions in the mine such as exposure to dust, heat and other chemical substances used with the mine were evaluated.
