Open-Pit Mining Methods

The cost of this preparatory work is obviously a charge against the cost of mining the ore, each ton of which must bear its proportionate share. As the stripping-ore ratio (volume or tons of overburden and capping to tons of ore made available for open-pit mining) increases, obviously the cost of stripping per ton of ore increases.
