Waste Rock


Waste rock piles are a common earth structure resulting from extensive mining operations. Such structures can often lead to acid rock drainage (ARD) if the flows into waste rock are not minimized. There are also potential slope stability issues.


SVFLUX and SVSLOPE can be used in order to model the flow through a waste rock pile or the stability. Complex geo-strata can be modeled with either package. This complex strata is often necessary due to the coarse-fine layering of rock material. The influences of any particular long-term cover design can be evaluated with SVFLUX. The representation of a single contaminant movement through a waste rock piles can also be simulated with the ChemFlux software.

Please note that most of these models can be downloaded through our SVOffice product suite.

Acid rock drainage (ARD) is the attributed to the complex interaction of physical, hydrological, geochemical, and microbiological process (Wels et al). This example presents the analysis of the water flow, heat flow and air flow in waster rock piles using a triple coupling numerical model supplied with the software of SVAirflow, SVFlux and SVHeat. The purpose of this example is to demonstrate the application of the SVOffice software to understanding the dominant process in a waste rock pile.

The conceptual model for a waste rock pile is that heat is generated due to the oxidation of pyrite deep in the pile in the presence of oxygen and moisture. The heat source results in convective currents in the waste rock pile, which affects the flow of both air and water. This numerical example will result in a greater understanding of these flows.
