Abstract
ABSTRACT Research has shown that broken rock on conveyor transport systems can contribute upwards of 50% toward the overall heat load in underground mines. However, few studies have made significant efforts to predict the temperature distribution of the ore and air simultaneously, which can help implement heat management strategies. The present investigation explores a transient, analytical heat transfer model to track ore-pile temperature distributions along conveyor systems in an example underground mine. Production rate, ambient conditions, ore pile thickness, and belt velocity are adjusted to evaluate the effect on dry and wet bulb temperatures. Model results indicated a total ore pile heat flow in the range of 4.2–5.2 MW, where higher heat transfer rates reflect winter ambient conditions and maximum production rates.
