Although single-level production is rarely used in an open-pit mine, bench stripping ratio can be used as a reference indicator for theoretical analysis. In addition, the amount of ore in a horizontal bench is the basic data for calculating the average stripping ratio and balancing production stripping ratio.

Canada, Mexico and Spain are other significant producers of raw gypsum. In all, more than 90 countries produce gypsum. In most open pit gypsum operations, benches are drilled and blasted using ammonium nitrate as the explosive. Because gypsum is so soft, most drills can drill through it at a rate of roughly 23 ft per minute.
