| Abstract: | Summary This paper describes the results from a continuing research project started in 1984, which is investigating improved methods for predicting the underground climate in hot mines. The Homestake Gold Mine in South Dakota was the site for testing methods, based on radial heat flow theory, to measurein situ values of the thermal conductivity and diffusivity of rock. The methods used proved to be quite within the capability of mine staff to carry out for themselves. The results were acceptable and verified thatin situ thermal rock properties can differ considerably from laboratory determined values, in this case by a factor of approximately two.A mine climate simulation program, CLIMSIM, was applied to case studies from the Homestake mine using the measured thermal rock parameters. The results showed good correlation between the measured and simulated values. |
