Análise do teor de corte na mina de cobre do Sossego-PA.

Abstract

Cut-Off quality is the basic parameter for mining economic definition. It is the ore substance which is capable of paying the piowings operations, its process and commercialization. Hence, this paper aimed at developing a series of very good plows for the coming next five years of the copper mine at Sossego, In order to achieve such a task, it was necessary to make a survey of the optimization parameters to define the armhole and the cutting quality variable profile, as well as to quantify the cutting quality analysis impact in the total movement annual rhythm. Two softwares have been used such as: "Genicom®" and "Whittle®". The former was used for resources model manipulation, whereas the latter was used to define the final limits of the digs and the Lane algorithm so as to serve as a simulation and optimization for the cutting quality. It was then concluded that the best sequencing of plows is the one whose quality varies within the years. This study is thus a contribution to signal the increase in both the
