Drilling grid blasting upgrading based on Geological Strength Index (GSI), case “La Maruja” mine, Colombia
Having proper rock masses characterization is of great importance in underground mining works to make the right decisions in terms of sustenance and other tasks like is the case of drilling and blasting.

Se plantea la construcción de una tabla geomecánica basada en el GSI a través de la cual se pueda tomar la decisión de que configuración de malla de perforación que a aplica para cada tipo de roca. Ello permite mejorar los ciclos de producción y consumo de explosivos en las voladuras. Dicha tabla se crea a partir de ensayos experimentales en voladuras de los paneles con distintas configuraciones geométricas de mallas de perforación que oscilan entre espaciamientos de 60x60cm y 80x80 cm; y su principal parámetro a garantizar es una granulometría máxima de 30 cm tras la voladura logrando reducir los costos en un 24,6%.application/pdfspaUniversidad Nacional de Colombia Sede Medellín.
