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.
