Optimization of Haul Road Geometry for Safe and Efficient Movement of HEMM in Opencast Mines
Year: 2026
Type: article
Abstract: Haul roads are a vital component of opencast mining operations, significantly influencing productivity, safety, fuel efficiency, and equipment longevity. Poorly designed haul roads result in increased rolling resistance, excessive fuel consumption, higher maintenance costs, and elevated accident risks. This study focuses on optimising haul road geometry and maintenance practices to enhance operational efficiency and ensure safe movement of Heavy Earth Moving Machinery (HEMM). The research integrates field observations, analytical modelling, and empirical design methods to evaluate key geometric parameters such as road width, gradient, curvature, and cross slope. The study also examines rolling resistance, grade resistance, and their combined impact on haul truck performance and fuel consumption. Maintenance practices such as grading, watering, and compaction are analysed for their role in sustaining road quality. Results indicate that optimised haul road design significantly reduces cycle time, fuel consumption, and operating costs while improving safety conditions. The study proposes a cost-effective framework for haul road design and maintenance, incorporating modern technologies such as GPS monitoring and condition-based maintenance systems. The findings provide practical guidelines for mine planners and engineers to achieve sustainable and efficient mining operations.
