When the open pit at Sacramento Hill, Bisbee, Ariz., became so deep that hauling ore from the pit was too expensive, the deep ore was mined by glory-holing. In 1929, 574,000 tons and in 1930, 304,000 tons were mined by this method. The bottom of the old pit was oval, about 450 feet long and 400 feet wide.

Open pit mining. One precondition for open pit extraction is that the ore body extends up to the surface or is not covered by an excessively thick layer of soil or rock. In most open pit mines, ore is extracted by so-called benching. The mining method is based on the ore being extracted in "benches" at successively lower levels.
