摘要

本文主要研究露天采矿的排序和调度问题，考虑中期水平的装载设备分配。本研究考虑到存在一个非均质装载设备队和两种可采材料，即矿石或废石。对于矿石的开采，考虑了以下要求:混合物质量，破碎机，加工厂的能力和库存，称为ROM库存。在这种情况下，我们提出了一个混合整数线性规划的数学模型，该模型由一个算法支持，该算法负责在每个模型运行时移动时间范围，旨在生成以最优性解决的挖掘顺序。这些订单共同描述了装载设备的采矿计划。

Mathematical model and supporting algorithm to aid the sequencing and scheduling of mining with loading equipment allocation

This paper focuses on the sequencing and scheduling problem of open pit mining, with the allocation of loading equipment considering a medium-term horizon. This study considers the existence of a heterogeneous loading equipment fleet and two types of mineable material, namely ore or waste rock. For the mining of ore, the following requirements are taken under consideration: the mixture quality, a crusher, the processing plant capacity and a stockpile, called ROM stockpile. In this context, we present a mathematical model in mixed integer linear programming, supported by an algorithm that is responsible for moving the time horizon at each model run, aiming to generate mining orders resolved with optimality. Together, these orders describe the loading equipment mining plan.

期刊介绍： REM – International Engineering Journal (antigua REM – Revista Escola de Minas) es la primera revista técnica de Sudamérica. Fue fundada en enero de 1936 por los estudiantes de la Escuela de Minas de Ouro Preto y desde entonces se ha especializado en la publicación de artículos en las áreas de la Ingeniería Civil, Geología, Metalurgia y Materiales y, Minería y Mecánica y Energía. Su objetivo es servir como un medio de publicación para los trabajos técnicos y científicos originales de investigadores nacionales y extranjeros en esas áreas. Contribuciones originales (artículos y cartas) son aceptadas. Artículos de revisión dependen de la invitación y/o análisis de los Editores. El envío de artículos para su publicación implica que el trabajo no ha sido publicado previamente, que no está siendo presentado para su publicación en otra revista y no se publicará en otro lugar, en la misma forma, sin el permiso, por escrito, de los Editores/Autores.
