REVISTA MINERÍA 540 | EDICIÓN SEPTIEMBRE 2022

MINERÍA la mejor puerta de acceso al sector minero MINERÍA / SEPTIEMBRE 2022 / EDICIÓN 540 160 y 219.7 ton (100%) para la flota 793D, con lo que se puede deducir que la flota 793C carga 3.3 toneladas más que los 793D. Para determinar un payload target para ambas flotas se hizo una simulación por cada una con targets mayores a su 100%, para hallar el nivel óptimo y no generar daños a ninguna. Finalmente se identificó que el payload target óptimo es de 245 ton (110%). Acciones de aseguramiento de mejora  Se realizaron monitoreos periódicos y correcciones en campo para garantizar el correcto estado de la balanza y display de los camiones.  Observaciones de tarea dispatch para control de payload en tiempo real, mediante ingreso a pantalla VNC camión/pala y cámaras de mina. Adicionalmente en el sistema dispatch se cuenta con dashboard en tiempo real para controlar cargas bajas, altas, sobrecargas y distribución de cargas a través de la Campana de Gauss. A parte de poder controlar el payload, en el dashboard de la Figura 13 se puede hacer seguimiento a KPI como productividad de equipos, disponibilidad, velocidades y EFH. El dashboard de la Figuera 14, se utiliza para llevar el control de una buena distribución de cargas alineadas al target objetivo, haciendo seguimiento por guardia, equipos de carguío (palas y excavadoras), operadores y flota de camiones. fleet; it can be deduced that the 793C fleet carries 3.3 tons more than the 793D fleet. To determine a payload target for both truck fleets, a simulation was made for each one with targets greater than 100%, in order to find the optimal target without causing damage to either fleet. Finally, it was determined that the optimum payload target is 245 tons (110%). Improvement Assurance Actions  Periodic monitoring and field corrections were made to ensure the correct condition of the trucks' balance and display.  Dispatch task observations for real-time payload control by means of VNC display input to truck/ scooptram and mine cameras. Additionally, the Dispatch system has a real-time dashboard to control low loads, high loads, overloads, and load distribution through the Gaussian Bell. In addition to being able to monitor the payload, the dashboard in Figure 13 can be used to track KPIs such as equipment productivity, availability, speeds and EFH. The dashboard in Figure 14 is used to keep track of a good load distribution aligned to the intended target, tracking by guard, loading equipment (scooptrams and excavators), operators and truck fleet.  Field task observations for loading and haulage operators by the Mine Supervisor, correcting and reinforcing payload management aligned to the new target.  Daily, weekly, biweekly, and monthly control and feedback of general and on-call load distribution. Figure 16 shows a report of the general and on-call load distribution curves, which is done on a daily, weekly, and monthly basis, in order to correct and control low or high loads. These curves are also used as part of the talk given before the start of each on-call shift, to inform operators about the payload project and to improve the distribution of target-oriented loads. Methodology The methodology used in this study consists of data collection, processing, and analysis. Data Collection Data was collected on payload per truck and scooptram for the year 2021; such data was obtained from the Mine Operate system database of the Mine Operations area of Newmont Yanacocha.
