Resumo: | In open pit mining, in the short term, the mining plans are subdivided into quarterly, monthly, weekly and daily operations. Monthly, the short-term planner defines the polygons, which comprise successive mining advances. These ore quality and tonnage parameters are previously determined by the mill. Traditionally, traverses are designed without a proper systematic approach. The interactions performed to obtain the specifications required by the plant are limited. There is a demand for studies involving optimization techniques for minimum mining units, helping the design of the ore, in order to minimize the variability in grade and maximize the recovery of the plant. This article proposes the adaptation of two optimization algorithms – Floating Cone and Floating Stope, traditionally used to define underground pits and highlights. A dimension value equal to zero was assigned to the support pillars, approaching the chambers and pillars method to a bench method, to configure a behavior close to open pit mining. The study proved that both methodologies presented satisfactory results. Despite the need for manual adjustments, discarding shared blocks, the Floating Cone proved to be a more selective system, especially for higher cut grades. |

Mensualmente, el planificador coyuntural define los polígonos, que comprenden los sucesivos avances mineros. Estos parámetros de tonelaje y calidad del mineral son determinados previamente por el molino. Tradicionalmente, las poligonales se diseñan sin un enfoque sistemático adecuado. Las interacciones realizadas para obtener las especificaciones requeridas por la planta son limitadas. Existe una demanda de estudios que involucren técnicas de optimización de unidades mínimas de minado, ayudando al diseño del mineral, con el fin de minimizar la variabilidad en la ley y maximizar la recuperación de la planta. Este artículo propone la adaptación de dos algoritmos de optimización – Floating Cone y Floating Stope, tradicionalmente utilizados para definir tajos subterráneos y realces. Se asignó un valor de dimensión igual a cero a los pilares de apoyo, aproximando el método de cámaras y pilares a un método de banco, para configurar un comportamiento cercano a la minería a cielo abierto. El estudio comprobó que ambas metodologías presentaron resultados satisfactorios. A pesar de la necesidad de ajustes manuales, descartando bloques compartidos, el Cono Flotante demostró ser un sistema más selectivo, especialmente para leyes de corte más altas.Na mineração a céu aberto, no horizonte de curto prazo, é realizado a subdivisão dos planos de lavra em trimestral, mensal, semanal e diário da operação. Em um horizonte mensal, um planejador de curto prazo define as poligonais, que compreende os sucessivos avanços de lavra, satisfazendo parâmetros de qualidade e tonelagem de minério fixadas previamente pela usina. As poligonais, tradicionalmente, são projetadas sem uma devida abordagem sistemática. Logo, as interações realizadas para obter as especificações exigidas pela usina é limitada. Portanto, há uma demanda por estudos envolvendo técnicas de otimização de unidades mínimas de lavra, auxiliando o delineamento do minério, de modo a minimizar a variabilidade em teor e maximizar a recuperação da usina, além de fornecer base quanto a tomada de decisão diária pelo planejador de curto prazo. Esse artigo propõe a adaptação de dois algoritmos de otimização – Cone Flutuante e Stope Flutuante, tradicionalmente utilizados para a definição de cavas e realces subterrâneos. Foi atribuído um valor de dimensão igual a zero para os pilares de sustentação, aproximando o método de câmaras e pilares a um método de bancadas, para configurar um comportamento próximo a lavra em céu aberto. O estudo comprovou que ambas as metodologias apresentaram resultados satisfatórios. Apesar da necessidade de ajustes manuais, descartando blocos compartilhados, o Cone Flutuante mostrou ser um sistema mais seletivo, principalmente para teores de corte mais elevado.
