Abstract
La presente investigación tiene como finalidad aplicar un modelo matemático para
diseñar una malla de perforación y voladura, que será aplicada en la labor de estudio para
optimizar el avance de esta. El método matemático elegido es el de Holmberg (1979).
En esta investigación, se emplea un enfoque metodológico cuantitativo así mismo
para el proyecto de investigación de utilizó el diseño pre-experimental. La labor donde se
realizar la investigación es el ACC 8792.
En el proceso pre-implementación analice 20 disparos realizados en la labor en
estudio, y para el post-implementación recolecte los datos de 15 disparos realizados con la
malla de perforación y voladura propuesta. Primero estableceremos una línea base con los
datos de pre-implementación, donde consideraremos datos de consumo de explosivos,
accesorios de voladura y aceros de perforación. Así como el avance de cada disparo, luego
estos datos fueron procesados para obtener las estadísticas descriptivas de los indicadores
mina (KPI’s) tales como Avance por disparo, Factor de carga, Factor de avance y Costo por
metro de avance. A continuación, diseñe la malla de perforación y voladura a proponer, para
posteriormente implementarla en la labor en estudio. Luego de hacer unos ajustes prácticos
insitus en la labor, propuse un estándar nuevo de malla a la cual daré seguimiento para
recolectar los datos de consumo y de avance de cada disparo. Procese los datos con el mismo
procedimiento que para la pre-implementación. Finalmente compare los resultados del pre y
post obteniendo un ahorro de 13.4% en los costos de perforación y voladura, que representa
cerca de 17 dólares por metro de avance, y una mejora en los indicadores tales como Avance
por disparo en 5,5%, el Factor de Avance en -21,8% y el Factor de Carga de -22,0%.
The purpose of this research is to apply a mathematical model to design a drilling and blasting mesh, which will be applied in the study work to optimize its progress. The mathematical method chosen is that of Holmberg (1979). In this research, a quantitative methodological approach is used and the pre-experimental design was used for the research project. The work where the research will be carried out is ACC 8792. In the pre-implementation process, analyze 20 shots made in the work under study, and for post-implementation, collect data from 15 shots made with the proposed drilling and blasting mesh. First we will establish a baseline with pre-implementation data, where we will consider consumption data for explosives, blasting accessories and drilling steels. As well as the advance of each shot, these data were then processed to obtain the descriptive statistics of the mine indicators (KPI's) such as Advance per shot, Load factor, Advance factor and Cost per meter of advance. Next, design the drilling and blasting mesh to be proposed, to later implement it in the work under study. After making some practical in-situ adjustments to the work, I proposed a new mesh standard that I will monitor to collect consumption and progress data for each shot. Process the data with the same procedure as for pre-implementation. Finally, compare the pre and post results, obtaining a saving of 13.4% in drilling and blasting costs, which represents about 17 dollars per meter of advance, and an improvement in indicators such as Advance per shot by 5.5%, the Advance Factor at -21.8% and the Load Factor at -22.0%.
