Evaluación de la eficiencia en la perforación de barrenos con máquina en una mina subterránea mediante simulación

Abstract

Se realiza una evaluación de la eficiencia en la operación de perforación de barrenos en una mina subterránea, mediante toma de tiempos estándar y simulación. Este estudio considera todas las actividades que realiza el operador de la máquina perforadora de barrenos (Jumbo) para desempeñar su trabajo. Para este análisis se considera la jornada de trabajo, esta empieza desde el traslado de la aduana a mina, luego de mina al lugar de trabajo y al final de la jornada el regreso a la aduana. Para analizar la variación presente en este proceso de perforación de barrenos se utiliza simulación, con el objetivo de evidenciar la dinámica que se vive el día con día en una mina subterránea. Los resultados del estudio se concentran en tres grandes rubros, estos son el tiempo de traslado del operador, los tiempos de operación de perforación de barrenos, y por último los tiempos muertos los cuales son considerados como actividades que no agregan valor pero que son necesarios para realizar el trabajo, como puede ser demoras, fallas de máquina, sin actividad, re-trabajos, falta de herramental, etc. Los resultados demuestran que se destina en promedio un 23% del tiempo disponible al traslado del operador en mina, un 22% al tiempo de operación de perforación de barrenos con jumbo, para las actividades de pueble (Junta) y comida se destina un 15% del tiempo, y un 40% restante al tiempo muerto.
