THE IMPORTANCE OF ACCURATE ROCK PROPERTY AND VIRGIN ROCK TEMPERATURE DATA IN VENTDLATION AND COOLING PLANNING REQUIREMENTS

摘要

This paper investigates why it is critical for a mine to accurately determine thermal rock properties and virgin rock temperatures. Theoretical simulations of deep mining production zones have demonstrated that thermal conductivity (k), virgin rock temperatures and specific heat (c_p) significantly impact rock heat predictions which can be the dominant component of a mine's heat load. Natural variability in these factors showed that realistic errors can have a significant effect on mine heat loads. This can ultimately affect miner safety and introduces risk to the viability and sustainability of a project.
