Heat source determination in waste rock dumps

摘要

oxidation of sulfidic materials in waste rock dumps leads to a degradation in water quality and consequent environmental impacts through acid mine drainge. predicting the pollutant loads from a dump requirs the sulfidic oxidation rates be determined. Oxidation generates heat at a rate proportional to the oxidation rate. The temperature profile of the dump depends upon the distribution and magnitude of heat sources, the thermal conductivity of the dump material, heat transport mechanisms and the dump boundary conditions (heat losses and insolation).
