description | Se presenta un método empírico-analítico para el diseño de pilares de rocas en la minería subterránea de vetas auríferas en Colombia, que parte de la observación de casos en algunas de las condiciones geológicas de mayor producción en el país y otras experiencias internacionales. La propuesta es centrada en la observación de los mecanismos de ruptura de pilares existentes, en levantamientos de campo, en mecánica de rocas experimental y en análisis estático. La definición del tamaño del pilar se fundamenta en el cumplimiento de requerimientos de estabilidad por evaluación entre la resistencia disponible y los esfuerzos actuantes. El método es expuesto con la intención de facilitar su adopción por parte de la pequeña y mediana minería. In this work is presented an empirical-analytical method for the design of rock pillars in the underground mining of gold veins in Colombia. The proposal is focused in the observation of the failure mechanisms of existing pillars from real mines, field surveys, experimental rock mechanics and static analysis. The definition of the size of the pillar is based on compliance with stability requirements by evaluation between the available strength and the acting forces. The method is presented with the intention of facilitating its adoption by small and medium-scale mining. |
