Diurnal Thermal Flywheel Influence on Ventilation Temperatures in Large Underground Mines

Craig Stewart, Saiied M. Aminossadati, Mehmet S. Kizil, Tim Andreatidis.

The daily temperature variance between daytime and night-time can have a significant influence on the ventilation conditions within a mine. Air temperature variations are reduced as air travels further into a mine due to the storage and release of heat in rock boundaries and variations in heat transfer between...
