Modelo de Evaluación de las Causas de la Fatiga Laboral en Conductores de Minería Subterránea Utilizando el Ciclo PDCA

Work fatigue is a critical risk factor in underground mining, particularly among transport drivers, due to long working hours, lack of sleep, and the monotony of routes. These factors compromise worker safety and operational efficiency. To address this issue, an occupational health and safety management system was designed using the PDCA cycle (Plan, Do, Check, Act), which provides a structured framework to identify and mitigate fatigue-related risks. In the context of the Ticrapo mining project, located in Huancavelica, Peru, strategies such as scheduled breaks, task rotation, and continuous monitoring of drivers’ conditions were implemented. These actions, supported by surveys and historical incident analyses, allowed for the prioritization of critical areas and adjustments to safety measures. As a result, significant reductions in fatigue-related incidents and improvements in drivers’ working conditions were achieved. This management model not only enhances safety at the Ticrapo mining project but also offers a replicable approach for other mining operations facing similar challenges, contributing to the sector's sustainability and productivity.
