The main objective of the research was to determine the operating cost of replacing 24 m3 dump trucks with 32 m3 hoppers for ore hauling at the Minera La Mamita contract in Huamachuco. The methodology used was a non-experimental design, descriptive of the applicative type. The population consisted of all the hauling dumpers used in the mining operation at the La Mamita mining contract and the sample consisted of 24 m3 dumpers and 32 m3 hopper dumpers. The hypothesis was validated using the ANOVA statistical test with a probability of less than 5%, which obtained a critical F value of 5.14 and an F statistic of 74.02. The results obtained from the comparative evaluation highlighted that the hoppers outperform in technical specifications, offering a higher power of 560 HP and capacity of 32 m3. The time analysis revealed that the FMX 500 dump trucks average 30.09 minutes and the hoppers average hauling cycle times of 17.14 minutes, resulting in a reduction of 12.94 minutes per cycle. In financial terms, the cost per cycle for the dump trucks was 26.67 USD, in contrast to 19.17 USD for the hoppers, reflecting a substantial savings of 7.40 USD per cycle during the months of September to November 2023. Finally, it is concluded that replacing 24 m3 dump trucks with 32 m3 hoppers results in a 28% reduction in operating costs, which not only optimizes the hauling process but also increases the profitability of the Minera La Mamita contract.
