Durante la investigación, se viene ejecutando el XC 8657-SE que tiene una sección de 2.4m x 2.7m en el Nv. 3125 de la zona Chilcas bajo en la Minera aurífera retamas S.A. Al inicio de la investigación, la perforación y voladura se realizaba de manera empírica por parte del maestro perforista, obteniendo como resultados un avance ineficiente, sobredimensionamiento de la labor, inadecuada distribución de la energía explosiva teniendo como consecuencia los elevados costos de perforación y voladura en el frente de trabajo. En la actualidad en el XC 8657-SE se ha aplicado un diseño de malla de perforación y voladura realizado con cálculos adecuados para la distribución de los taladros y la energía del explosivo para la ejecución de este proyecto. El objetivo de esta investigación es aplicar un nuevo diseño de malla de perforación y voladura para lograr resultados favorables ...

In the training of University students, the effect of the use of Matlab software on academic performance has been evaluated in a group of repeating students of basic mathematics, quasi-experimental, quantitative research with a pre-experimental pre-test research design - post test with a single group; There was a sample of 48 repeating students distributed in a single group, using individual academic performance on the scale of 0 to 20; It is concluded that the use of Matlab mathematical software positively influences the academic performance of a group of repeating students
