is defined as the stripping ratio. Stripping ratios of 2:1 up to 4:1 are common in large mining operations. Ratios above 6:1 tend to be less economically feasible depending on the type of ore extracted. Once removed, overburden can be used for road and tailings' construction or may have a non-mining commercial value as a backfilling material.
