Improving Performance Of Soil Covers Over Waste Rock Dump

Abstract Soil covers over mine waste rock dump tops in dry climates are intended to limit the ingress of oxygen andor to limit the net percolation of rainfall infiltration into the underling potentially reactive waste rock excavated, in particular, on open pit mining. The climate in which the mine is located plays a key role. The aim of limiting the ingress of oxygen into the dump is to ...
