Sequenciamento de deposição do material de baixo teor referente às pilhas 3 e 4 do projeto posse: Amarillo Gold

Abstract

Scheduling of waste dumps, although little mentioned in the literature, is an important part of the set of steps involving mine planning. In order to improve the details of the mining plans carried out for the opening of the Posse Gold mine, Amarillo Gold Corp. Mining, the sequencing of the waste dumps 3 and 4 was performed, with a block model designed specifically for this paper. The dumps contain specific predefined content and design made feasible according to the geomechanical parameters stipulated. With the files provided and together with studies and techniques to define the best values to be used, the scheduling of the mine pit and, consequently, the scheduling of material deposition for two specific piles (3 and 4) was performed; thus, the premises of mining were adapted to the operational reality of mining. These dumps were scheduler in order to optimize the future use of marginal ores present in them.
