Abstract

Effective mine production planning is critical for improving operational performance in open-pit mining, particularly amid challenges related to heavy equipment management, limited working time, and rising operational costs. This study aims to optimize mine production planning to enhance operational efficiency through the application of quantitative optimization models. Using an applied quantitative approach within an operations research framework, the research is based on a case study of an open-pit coal mine in East Kalimantan, Indonesia. Secondary production data, including equipment capacity, effective working time, operational costs, and production targets, were analyzed. A linear programming model was developed to minimize production costs and maximize equipment utilization under operational constraints. The results demonstrate that the proposed optimization model yields more efficient production planning than existing practices, as reflected in reduced operational costs and improved equipment utilization without compromising production targets. This study provides practical recommendations for mine managers and contributes theoretically to the application of operations research in mining production management.
