Abstract
La baja productividad en el carguío y limpieza de mineral en la mina Poderosa
afecta el uso eficiente de equipos como el scoop y camiones de bajo perfil. Se
identificaron causas principales como deficiencias en el tiempo de ciclo de
carguío, baja disponibilidad mecánica, y problemas en la capacitación de
operadores. Estas afectan costos operativos, productividad y generan paradas
injustificadas.
Para abordar esta problemática, se propone optimizar el tiempo de carguío y
aumentar la capacidad de la cuchara del scoop R1300G. Esto se basará en
investigaciones previas que vinculan la productividad con el mantenimiento
adecuado y la eficiencia operativa, buscando mejorar los índices de gestión en
el área de carguío.
Es por ello que nos hemos planteado el objetivo general que es incrementar la
productividad del Scoop R1300G optimizando el tiempo de ciclo de carguío en el
nivel 2910 de la mina Poderosa y como objetivo específico 1, medir la
productividad del Scoop R1300G antes de la optimización del tiempo de ciclo de
carguío y como objetivo específico 2, medir la productividad del Scoop R1300G
después de la optimización del tiempo de ciclo de carguío.
Según el objetivo específico 1. se recopiló información sobre el "Tiempo
de ciclo de carguío" mediante la medición diaria de tiempos de acarreo,
incluyendo: tiempo de ida, llenado de cuchara, retorno, vaceado, efectividad
operativa, tiempos muertos e improductivos. Los datos se tomaron en una
cámara de carguío que funciona como estación de acopio para el scoop R1300G,
facilitando la logística del ciclo de acarreo. Se consideraron dos cámaras de
carguío en diferentes frentes de minado, manteniendo la misma distancia del
frente. Un asistente supervisó la toma de datos para minimizar sesgos y errores
en el registro.
Para el segundo objetivo específico, se trata la "capacidad de carga de la
cuchara" del Scoop R1300G, aumentando su tamaño de 4.1 yd³ a 4.4 yd³ para
mejorar la remoción de material por ciclo. Este cambio implica un análisis de las
xv
condiciones del lugar y capacitación del personal para asegurar la operación segura. Se implementa en tres etapas: evaluación de las dimensiones del entorno, capacitación del personal y despliegue de equipos en los frentes de minado.
La evaluación de la nueva capacidad se realiza en tramos de diferentes longitudes (60 a 150 metros), y se observa que el rendimiento disminuye con tramos más largos. La reducción en los tiempos de ciclo se logra por el aumento de la capacidad de la cuchara y la actualización de equipos obsoletos. Esto mejora la productividad al disminuir tiempos muertos. Además, se planifican capacitaciones para los operadores, esenciales para maximizar la productividad durante su turno.
Low productivity in the loading and cleaning of mineral at the Poderosa mine affects the efficient use of equipment such as the scoop and low-profile trucks. Key causes identified include deficiencies in loading cycle time, low mechanical availability, and training issues for operators. These factors impact operational costs, productivity, and lead to unjustified downtime. To address this issue, it is proposed to optimize loading time and increase the scoop capacity of the R1300G. This will be based on previous research linking productivity with proper maintenance and operational efficiency, aiming to improve management indices in the loading area. Thus, our general objective is to increase the productivity of the R1300G scoop by optimizing the loading cycle time at level 2910 of the Poderosa mine. Specific objective 1 is to measure the productivity of the R1300G scoop before optimizing the loading cycle time, and specific objective 2 is to measure the productivity of the R1300G scoop after optimizing the loading cycle time. According to specific objective 1, information was collected on the "Loading Cycle Time" through daily measurements of haul times, including: travel time, scoop filling time, return time, dumping time, operational effectiveness, downtime, and unproductive time. The data were collected in a loading chamber that serves as a storage station for the R1300G scoop, facilitating the logistics of the hauling cycle. Two loading chambers at different mining fronts were considered, maintaining the same distance from the front. An assistant supervised data collection to minimize biases and errors in recording. For the second specific objective, the "load capacity of the scoop" of the R1300G is addressed by increasing its size from 4.1 yd³ to 4.4 yd³ to improve material removal per cycle. This change involves analyzing site conditions and training personnel to ensure safe operation. It is implemented in three stages: evaluation of the environment's dimensions, personnel training, and deployment of equipment at the mining fronts. xvii The evaluation of the new capacity is conducted over different lengths (60 to 150 meters), and it is observed that performance decreases with longer stretches. The reduction in cycle times is achieved through the increased scoop capacity and updating obsolete equipment. This improves productivity by reducing downtime. Additionally, training for operators is planned, which is essential to maximize productivity during their shifts.
