Abstract
El objetivo principal de la investigación fue analizar los costos operacionales y valorizaciones para determinar la rentabilidad en la construcción de la labor cortada 5000 en la contrata minera EJMAC, 2023.
La metodología que utilizó es de diseño no experimental, descriptivo del tipo aplicativo. La población estuvo conformada las labores mineras presentes en la contrata minera EJMAC y la muestra por la labor cortada 5000 de la misma contrata minera, para evaluar la significancia estadística se aplicó la prueba ANOVA, arrojando un valor de F de 6.72, que supera el valor crítico de 3.40, con un (p<0.05). Los resultados obtenidos fueron que se logró analizar los costos operacionales en la construcción de la labor cortada 5000, siendo el costo de perforación y voladura de 1030.39 soles por metro, de carguío y acarreo de 225.46 soles; sostenimiento, con un importe de 673.64 soles; ventilación, por un valor de 422.17 soles; de servicios fue 401.50 soles y el de extracción fue de 248.73 soles por metro de avance. Esto arrojó un costo operativo total de 3001.89 soles por metro lineal. También se analizó las valorizaciones en la construcción de la labor cortada 5000, resultando en una valorización anual de 2,022,725.39 soles para el periodo de abril a diciembre de 2023. La rentabilidad anual de la empresa, derivada de la construcción de la labor cortada 5000, fue de 968,761.81 soles. Se calculó además un Valor Actual Neto (VAN) de 1,768,729.63 soles, una Tasa Interna de Retorno (TIR) del 84% y una ratio Beneficio/Costo (B/C) de 2.68.
Finalmente se llega a la conclusión que, basándose en el análisis de costos operacionales y las valorizaciones, la construcción de la labor cortada 5000 en la contrata minera EJMAC, 2023 resulta ser una inversión completamente rentable.
The primary objective of the research was to analyze operational costs and valuations to determine the profitability of constructing the Cut 5000 project at the EJMAC mining contractor in 2023. The methodology used is a non-experimental, descriptive design of the applicative type. The population consisted of the mining operations present at the EJMAC mining contractor, with the sample being the Cut 5000 project from the same contractor. To evaluate statistical significance, the ANOVA test was applied, yielding an F value of 6.72, which exceeds the critical value of 3.40 (p<0.05). The results obtained showed that the operational costs for the construction of the Cut 5000 project were successfully analyzed. The drilling and blasting cost was 1030.39 soles per meter, loading and hauling cost was 225.46 soles; support cost was 673.64 soles; ventilation cost was 422.17 soles; service cost was 401.50 soles, and extraction cost was 248.73 soles per meter of advance. This resulted in a total operational cost of 3001.89 soles per linear meter. Additionally, valuations for the construction of the Cut 5000 project were analyzed, resulting in an annual valuation of 2,022,725.39 soles for the period from April to December 2023. The annual profitability of the company, derived from the construction of the Cut 5000 project, was 968,761.81 soles. Furthermore, a Net Present Value (NPV) of 1,768,729.63 soles, an Internal Rate of Return (IRR) of 84%, and a Benefit/Cost (B/C) ratio of 2.68 were calculated. In conclusion, based on the analysis of operational costs and valuations, the construction of the Cut 5000 project at the EJMAC mining contractor in 2023 is found to be a completely profitable investment.
