Abstract
El objetivo principal de la investigación fue analizar las interferencias operacionales de
los equipos de carguío debido a la voladura de rocas y su incidencia en la rentabilidad de la
empresa de transportes e inversiones CEDAR S.R.L.
La metodología que utilizó fue de diseño no experimental, descriptivo del tipo
aplicativo. La muestra de estudio se conformó por los equipos excavadora 950 EL-01,
excavadora 950EL-02, excavadora 750DL-01 y cargador frontal L260H-01 de la empresa
contratista CEDAR S.R.L. La data se recolecto mediante análisis documental, y el control de
calidad de datos se realizó mediante probabilidad, siendo menor al 5% con un valor crítico de
4.35, un estadístico F de 33.46 y un p-value<0.05. Los resultados obtenidos indicaron que el
tiempo por cada voladura fue de 0.58 horas, generando un total de 70.58 horas en 121
interferencias operacionales en un periodo de enero a noviembre de 2023. El tiempo perdido
S.R.L.
por interferencia operacional fue de 211.75 horas para excavadoras y de 70.58 horas para el
cargador frontal, generando un total de 282.33 horas, logrando 9804.19 horas operativas para
la excavadora y 3396.26 horas para el cargador frontal. Asimismo, la rentabilidad proyectada
de la empresa fue de 1279056.62 US$, donde la influencia de las interferencias operacionales
fue de 2.10%, con un valor de 23292.50 US$ para las excavadoras y 4799.67 US$ para el
cargador frontal, generando un total de 28092.17 US$ perdidos por interferencias
operacionales, generando una rentabilidad total de 1250964.45 US$ de la empresa CEDAR
Finalmente se llega a la conclusión que las interferencias operacionales de equipos
carguío causados por voladura de rocas influyen en la rentabilidad de la empresa minera
CEDAR S.R.L.
The main objective of the research was to analyze the operational interferences of the loading equipment due to rock blasting and their incidence on the profitability of the transport and investment company CEDAR S.R.L. The methodology used was non-experimental, descriptive, and applicative in nature. The study sample consisted of the excavator teams 950 EL-01, 950EL-02, 750DL-01, and the front loader L260H-01 from the contractor company CEDAR S.R.L. Data was collected through document analysis, and data quality control was conducted using probability, with a critical value below 5% at 4.35, an F-statistic of 33.46, and a p-value < 0.05. The results indicated that the time per blast was 0.58 hours, generating a total of 70.58 hours across 121 operational interferences from January to November 2023. The time lost due to operational interference was 211.75 hours for excavators and 70.58 hours for the front loader, totaling 282.33 hours, achieving 9804.19 operational hours for the excavator and 3396.26 hours for the front loader. Additionally, the projected profitability of the company was US$ 1279056.62, where the influence of operational interferences was 2.10%, equating to US$ 23292.50 for the excavators and US$4,799.67 for the front loader, generating a total loss of US$ 28092.17 due to operational interferences, resulting in a total profitability of US$ 1250964.45 for the company CEDAR S.R.L. Finally, it is concluded that the operational interferences of loading equipment caused by rock blasting influence the profitability of CEDAR S.R.L. mining company.
