Heat recovery systems in underground mines are not common. Little research has been carried out on the subject and with the increased price of energy, these systems will become more and more relevant for the mine sites located in cold regions of the world.


The development of a computer software application to evaluate the feasibility of recovering heat from exhaust mine air, using input data from a given mine site. The software will help determine cost benefits of installing an exhaust heat recovery system to heat mine intake air during cold periods. It will also determine the total energy cost savings per year and a capital cost of the system to obtain an approximate payback period.
