The generation of heat in underground spaces due to working activities is a factor that influences production and productivity rates. This paper analyses the heat generation in an underground mine and provides a number of approaches to enhance the ventilation conditions using electrical, instead of diesel machines. This assessment has been carried out using theoretical equations and modelling software. Investigations prove that sensible and latent heat would be reduced by around 50% and 84% respectively if the change were applied in the case study. This reduction on heat input to the ventilation system would improve the workplace environment because of lower effective temperatures and gas concentrations, which would result in better safety conditions and higher employee efficiency.
