The earliest continuous surface miner used for excavating and loading soft and loose material is the elevating grader. However, they are unsuitable for stiff material and cannot negotiate boulders [6].The first surface miner (of Wirtgen make, Germany) was sold in 1983 to make on roads in gypsum mine in South Africa.

At the Hope mine these higher beds are at slightly higher elevation than the surface at the old mine shaft. This gypsum was quarried from several pits before the deeper bed was mined. Near the Solomon mine and the mouth of Gypsum Creek a higher bed is exposed in a field in sec. 2, T. 14 S., R. 1 W., less than a mile east of the beds …
