Rapid Evaluation Of Rock Thermal Parameters At The Lucky Friday Mine, Ian J. Duckworth
Rapid Evaluation Of Rock Thermal Parameters At The Lucky Friday Mine, Ian J. Duckworth
U.S. Mine Ventilation Symposium
In many hot mines a large portion of the total heat load is associated with the surrounding strata. In order to maintain acceptable underground environmental conditions, the mine heat load must be controlled by the ventilating airstream, and in certain cases by mechanical refrigeration. To compute existing, or future heat additions from the surrounding rock, certain parameters must be -determined. These parameters include the rock thermal conductivity, thermal diffusivity, and the geothermal gradient (with relation to a virgin rock datum). These rock thermal parameters are typically estimated from published literature, or evaluated by laboratory or in-situ measurements. Presented in the …
