ResumoEste artigo propõe uma metodologia para a construção de um Referencial Estatístico para a Utilização Física de equipamentos de mina. Para tanto, calcula-se um valor mensal (RE) apoiando-se em conceitos importantes para a operação de mina e que estão e inter-relacionados, como o comportamento sazonal da precipitação pluviométrica, o Teorema do Limite Central e a Gestão da Lacuna de Resultado. A metodologia proposta foi aplicada em uma mina de ferro a céu aberto e às frotas de transporte de um complexo minerador no Norte do Pará. Palavras-chave: Metodologia; Referencial; Estatístico. METHODOLOGY FOR CONSTRUCTION OF STATISTICAL REFERENCE OF PHYSICAL USE OF MINE EQUIPMENT'S AbstractThis article proposes a methodology for the construction of a Statistical Reference for the Physical Use for mine equipment's. Therefore, we calculate a monthly value (RE) relying on important concepts for mine operation and are and interrelated, as the seasonal behavior of rainfall, the Central Limit Theorem and Management of Gap Result. The proposed methodology was applied in an iron ore open pit mine and on transport fleets of a mining complex in northern of Pará state.
