Abstract
El Proyecto Mina Chuquicamata Subterránea (PMCHS), asociado a obras de preparación minera, es responsable de la ejecución de trabajos mineros, civiles y de montaje e infraestructura, previos al inicio de la extracción de mineral.
La Vicepresidencia de Proyectos de Codelco, que es responsable de la administración del PMCHS, continuamente implementa mejoras en los diversos procesos. En este contexto surge, desde la Gerencia, la propuesta de una nueva metodología constructiva en desarrollos horizontales que promete aumentar los rendimientos y disminuir los plazos.
El objetivo de este estudio fue evaluar las mejoras en la productividad obtenidas, mediante una prueba piloto en el Nivel de Hundimiento, de la metodología denominada Célula de Trabajo Autónoma (CTA) y posteriormente evaluar su implementación en el Nivel de Producción.
Los resultados de la prueba piloto en Nivel de Hundimiento indican que la CTA fue exitosa durante la prueba piloto, aumentando el rendimiento en un 82% (de 310 m/mes a 565 m/mes) y el desempeño en un 40% (de 50 HH/m a 30 HH/m). Además, los indicadores vinculados a seguridad, uso de recursos y calidad constructiva también obtuvieron una mejora relevante.
La implementación de la CTA en el Nivel de Producción, evaluada mediante simulaciones, promete un aumento en el rendimiento de 35% (de 450 m/mes a 600 m/mes), considerando una estrategia constructiva que habilita una zanja a lo largo del macrob
The Chuquicamata Underground Mine Project (PMCHS), associated with mine preparation operations, is responsible for the execution of mining and civil labours, and assembly and infrastructure operations, prior to the start of mineral extraction. Codelco's Vice Presidency of Projects, which is responsible for the administration of the PMCHS, continually implements improvements in several processes. In this context, from the Management department arises the proposal of a new constructive methodology in horizontal developments that promises the increasing of the performance and the reduction of the lead time. The objective of this study was to evaluate the improvements in productivity obtained, throughout a pilot program at the Sinking Level, of the Autonomous Work Cell (CTA) methodology, and the later evaluation of its implementation at the Production Level. The results of the pilot test in Sinking Level indicate that the CTA was successful during the pilot test, increasing the efficiency by 82% (from 310 m/month to 565 m/month) and the performance by 40% (from 50 HH/m at 30 HH/m). In addition, the indicators related to safety, use of resources and construction quality also obtained a significant improvement. The implementation of the CTA at the Production Level, evaluated through simulations, promises an increase in the efficiency by 35% (from 450 m/month to 600 m/month), considering a construction strategy that enables a trench along the macroblock
