Abattage à front en chantier. [...] Si l'attaque s'effectue en partant du haut du chantier, on dira qu'on exploite par gradins droits - trous descendants - («underhand stoping»). L'inverse, c'est-à-dire l'exploitation en partant du bas - ou exploitation montante - est dite par gradins renversés («overhand stoping»). [...] L'exploitation par gradins droits [...] part du niveau supérieur. Les trous sont forés de haut en bas et l'on descend le minerai explosé par des chutes, jusqu'au niveau inférieur, puis on le transporte à la recette («station») du puits. 1, record 1, French, - exploitation%20par%20gradins%20droits
