Abstract
RESUMO O presente trabalho concentra-se na elaboração de referências técnicas locais e específicas para carga e transporte na fase de mina, contemplando macro indicadores de utilização física (UF - %) no transporte e produtividade (P -t/h) na carga, assim como seus sub indicadores de desempenho chave. Levando em conta perdas, restrições, referências técnicas e bibliografia relevantes. Indicadores de referências técnicas baseiam-se no mapeamento de gargalos e restrições de cada caso para definir estratégias e decisões a serem tomadas que levam a maiores ganhos operacionais, chamado de referência local. Através de dados históricos do sistema de despacho, condições de contorno da operação e referências técnicas o trabalho estabeleceu uma abordagem para estimar a referência local. Como produto estabeleceu metas de UF e P para o caso em questão, oferecendo percepções de ganhos na eficiência operacional considerando as restrições aplicadas. As percepções foram aplicadas à operação que apresentou ganhos significativos.
This work focuses on developing local and specific technical references for loading and transportation in the mine phase, including macro indicators of physical utilization (UF -%) in transportation, and productivity (P - t/h) as well as their key performance sub-indicators. Losses, constraints, technical references, and relevant literature are considered. Technical reference indicators are based on mapping bottlenecks and constraints in each case to define strategies and decisions that lead to greater operational gains, known as local references. Using historical data from the dispatch system, operational boundary conditions, and technical references, the work established an approach to estimating the local reference. The result was established UF and P targets for the case in question, offering insights into operational efficiency gains considering the constraints applied. These insights were applied to the operation, which demonstrated significant gains.
