Title
(EN) PASTE FOR USE IN MINING PROCESSES
(FR) PÂTE DESTINÉE À ÊTRE UTILISÉE DANS DES PROCÉDÉS MINIERS
Abstract
(EN)
Disclosed is a paste for use in mining processes, such as backfilling and cemented rock fill, to provide improved early and late-stage strength at a lower overall cost. The paste includes mine tailings, one or binding agents, engineering backfill and water. The engineering backfill fibers are typically plastic fibers obtained from plastic products, partially plastic products, recycled plastic products, or partially recycled plastic products. Also disclosed are methods of backfilling a portion of a mine and uses of the paste in mining processes.
(FR)
L'invention concerne une pâte destinée à être utilisée dans des processus miniers, tels que le remblayage et le remplissage de roche cimentée, pour fournir une résistance initiale et tardive améliorée à un coût global inférieur. La pâte comprend des résidus de mine, un ou plusieurs agents de liaison, un remblai d'ingénierie et de l'eau. Les fibres de remblai d'ingénierie sont typiquement des fibres plastiques obtenues à partir de produits en plastique, de produits partiellement en plastique, de produits en plastique recyclés ou de produits en plastique partiellement recyclés. L'invention concerne également des procédés de remblayage d'une partie d'une mine et des utilisations de la pâte dans des procédés miniers.
