Abstract
El propósito principal del estudio fue mejorar los parámetros de barrenación y
voladura para aumentar el avance lineal en la GL_642-S de la Sección VII – Minera
Yauliyacu, 2024.
El enfoque metodológico fue cuantitativo, tipo aplicada y diseño preexperimental,
en donde se tomó como población a el total de disparos realizados en los
frentes de avance horizontal de 3.5 m x 3.5 m de la sección VII y la muestra fue 30
disparos realizadas en la GL_641-S. Según lo obtenido en los resultados, se logró mejorar
los parámetros de P&V. al igual que se logró un incremento del 12.06% en el avance
lineal de la GL_641-S, pasando de 3.04 m a 3.41m, se logró reducir el F.C.L. de 44.17
Kg/m a 39.29 kg, el F.C. de 3.29 Kg/m3 a 3.02 Kg/m3 y el F.P. de 1.17 Kg/ton a 1.08
Kg/ton, lo representa una reducción del 11.0%, 8.2% y 7.7% respectivamente. Además,
se aplicó el algoritmo XGBoost para validar el incremento del avance lineal por disparo
con la mejora de parámetros de P&V.
Se concluye que con la mejora de parámetros de P&V, se logró incrementar el
avance lineal promedio por disparo, así como la reducción de los factores de voladura de
la sección VII.
The main objective of the study was to improve the drilling and blasting parameters to increase the linear advance in GL_642-S of Section VII – Minera Yauliyacu, 2024. The methodological approach was quantitative, applied type and pre-experimental design, where the total population was taken as the shots made in the horizontal advance fronts of 3.5 m x 3.5 m of section VII and the sample was 30 shots made in the GL_641- S. According to the results obtained, it was possible to improve the P&V parameters as well as an increase of 12.06% in the linear advance of the GL_641-S, going from 3.04 m to 3.41 m, it was possible to reduce the F.C.L. from 44.17 Kg / m to 39.29 kg, the F.C. from 3.29 Kg / m3 to 3.02 Kg / m3 and the F.P. from 1.17 Kg/ton to 1.08 Kg/ton, which represents a reduction of 11.0%, 8.2% and 7.7% respectively. In addition, the XGBoost algorithm was applied to validate the increase in linear feed per shot with the improvement of P&V parameters. It is concluded that with the improvement of P&V parameters, it was possible to increase the average linear advance per shot, as well as the reduction of the blasting factors of section VII.
