This paper aims to investigate the causes and consequences of inefficient maintenance operations at XYZ mine and their impact on organizational performance. The study follows an exploratory sequential mixed methods design that begins with a qualitative observation followed by a quantitative analysis of historical maintenance data. The findings of the study revealed significant inefficiencies, including engine failure, worn-out ground engagement tools, poor equipment condition and equipment accident damage as leading factors to frequent equipment breakdowns, heightened safety incidents and maintenance costs. The study also highlights safety issues stemming from non-conformance with maintenance protocols and inadequate safety training. Recommendations include implementing risk assessments before commencement of any operation, enhancing training programs, improving safety protocols, and considering investment in new equipment or comprehensive rebuilds. These measures aim to enhance equipment performance, lower maintenance costs, and increase safety, ultimately improving overall operational efficiency at the mine.
