Abstract
En el marco de la investigación del presente estudio se abordó la problemática de la falta de confiabilidad de equipos en la Operación Minera Segura, proponiendo como objetivo general para dar solución a este problema implementar una estrategia de mantenimiento para lograr mayor confiabilidad en los equipos de carguío y acarreo. La metodología es de tipo aplicada, naturaleza cuantitativa y diseño no experimental. La población estuvo conformada por los equipos utilizados por la empresa, tomando como muestra los equipos de carguío y acarreo. Se recolectaron datos a través de guías de observación y análisis documental, y se analizaron estadísticamente utilizando indicadores de mantenimiento como el tiempo medio entre fallas (MTBF), el tiempo medio para reparar (MTTR), porcentajes de disponibilidad y confiabilidad de los equipos, haciendo un comparativo entre los años 2021 (etapa diagnóstica) y 2022 (etapa de implementación). Los resultados evidenciaron que existe una mejora significativa en la confiabilidad y disponibilidad de los equipos de carguío y acarreo Operación Minera Segura durante el año 2022 tras implantar como estrategia el Mantenimiento Centrado en la Confiabilidad – RCM en comparación al año 2021 donde no se manejó ninguna estrategia. Se observó una reducción del 25% en los costos de mantenimiento y un 53% en los costos por indisponibilidad de equipos, lo cual representó un ahorro económico de US$732,500.00 anuales; se observó un incremento de la disponibilidad en los equipos, con rangos que van desde el 7% hasta el 11%; del mismo modo la confiabilidad aumento entre el 8% y el 12%. Se concluyó que la implementación de la estrategia RCM es factible y puede mejorar la confiabilidad de los equipos en la operación minera.

The methodology is of an applied type, of a quantitative nature and non-experimental design. The population was made up of the equipment used by the company, taking as a sample the loading and hauling equipment. The data was collected through observation guides and documentary analysis, and statistically analyzed using maintenance indicators such as mean time between failures (MTBF), mean time to repair (MTTR), availability percentages and reliability of the equipment, making a comparison between the years 2021 (diagnosis stage) and 2022 (implementation stage). The results showed that there is a significant improvement in the reliability and availability of the Safe Mining Operation loading and hauling equipment during the year 2022 after implementing Reliability Centered Maintenance - RCM as a strategy compared to the year 2021 where it was not implemented. handled no strategy. . A 25% reduction in maintenance costs and a 53% reduction in costs due to unavailability of equipment was observed, which represented economic savings of US$732,500.00 per year; an increase in the availability of equipment was observed, with ranges ranging from 7% to 11%; Similarly, reliability increased between 8% and 12%. It was concluded that the implementation of the RCM strategy is feasible and can improve the reliability of the equipment in the mining operation.
