Análise do rendimento operacional na frota de transporte da Mina Santa Felicidade

Abstract

This case study aimed to analyze the operational performance of the dump truck fleet at the Santa Felicidade Mine, owned by the company Harpia Mineração, located in Baixada Cuiabana, in the state of Mato Grosso. The study was conducted based on the application of widely used operational indicators, namely: Physical Availability, Physical Utilization, and Operational Performance. The data used were collected through the Mining Control system, developed by FAST2MINE, during the month of August 2024. To ensure data reliability, a sanitation and organization process was carried out, disregarding incomplete or invalid records. The analysis of the Key Performance Indicators (KPIs) showed that, although the average physical availability of the fleet was within acceptable parameters, the physical utilization and operational performance rates were below expectations, indicating operational bottlenecks in the use of available equipment. The three main causes of downtime that negatively impacted the indicators analyzed were identified by reading the equipment status records. Based on this, the 5 Whys methodology was applied to investigate the root causes of the occurrences, enabling a critical and systemic analysis of the operational, human and organizational factors involved. As a result, improvement proposals were drawn up, including alternating meal times, ending mineral research, creating a specific team for infrastructure, among other actions. The study highlights the importance of KPI management as a strategic tool for continuous improvement, contributing to increased productivity, resource optimization and assertive decision-making in mining operations in the implementation phase.
