The Computer Simulation of Climatic Conditions in Mines

Increases in mechanisation and mining at greater depths are leading to additional problems of heat and humidity in many mines. As a result there is now an escalating demand for temperature prediction simulations appli- cable to underground environments. After a brief review of the present situation with regard to world mining and the use of environmental programs, the paper goes on to discuss in moderate detail the mathe- matical modelling of the many parameters that govern the condition of the ventilating air in a mine. The development of a program that gives the temperature distribution for a mine ventilation system is then outlined. The practicality of the program is discussed and the presentation format for users is explained. Simplification of input data requirements and the acquisition of data from other planning programs are an integral part of the commercial application of this program.
