A computer simulation of mine air shaft thermodynamics

Several earlier investigations have been conducted into various aspects of heat problems in underground mines. The application of general gas laws and thermodynamics in the approach of mine ventilation has been helpful in elucidating certain difficulties associated with the subject. By combining several of the techniques perfected by these researchers and applying Carrier\u27s method of calculation for heat flow from exposed rock strata into a workable plan, a method was developed whereby it is possible to accurately and conveniently predict the quality of working environment at any point within a deep mine. The findings of this study may be of great value to designers in selecting economic optimums of labor, air conditioning and air transmission costs. They may be of further use in predicting underground conditions of fogginess, etc which can be remedied before the mining operations begin --Abstract, page ii
