O ritmo de lavra em operações a céu aberto é determinado, em geral, pelas capacidades de operação dos equipamentos de carga e transporte alocados às diversas frentes de lavra. Além disso, qualquer problema existente nas condições de trafegabilidade, como condições inadequadas das vias de transporte, pode comprometer diretamente no resultado planejado da produção, além de elevar os custos do processo. Foram analisadas as relações entre o estado de conservação das estradas de acesso no interior das minas a céu aberto e a vida útil dos pneus de caminhões fora-de-estrada, empregando-se os princípios do pensamento sistêmico. Um estudo de caso em uma mina a céu aberto de minério de ferro do Quadrilátero Ferrífero foi realizado, tendo como base resultados obtidos em dados históricos e visita técnica. Observou-se a importância do gerenciamento da manutenção das estradas e a conservação dos aspectos técnicos de projeto, uma vez que foram verificadas e confirmadas suas relações com o desgaste prematuro dos pneus. Os diagramas causais servem de referência tanto para identificação das ações de correção de problemas técnicos relativos à deterioração das vias quanto para as práticas gerenciais de manutenção adequada delas. 10
