smaller operations may be done with dynamite, but in most medium-to large-size operations, ammonium nitrate fuel oil mixture (AN-FO) is used as a low cost explosive. The rock is then extracted using power shovels or bulldozers. Underground Mining Underground operations are becoming more common, especially for limestone mining in
