    The method is based on mining the ore in descending levels through drilling and blasting. As the ore is removed, production moves successively downwards. The ore in the Svappavaara field's active open-pit mine, Leveäniemi, is extracted by mining the ore in descending levels. The thickness of the slabs, known as the bench height, is 15 metres, and the slabs are worked downwards
