Resumen

This article analyzes the applicability of an appropriate design of blasting engineering for an underground mine to be used in a Peruvian grain context through the data collection and observation method using the Bieniawski rock mass geomechanical classification system, average vein power weighting, and operational dilution of the pits. The generation of solutions is under both the McCarthy approach formula and final results analysis of the dilution behavior obtained in relation to the initial ones. Moreover, the database provided by a mining company is analyzed with respect to the geological conditions for the rock mass classification of the roof box and floor box to determine the quality of the rock, ore grades, power of the vein, and the percentage of dilution. Then we proceed to determine the continuity and thickness of the vein in a given block and analyze the dilution based on the fundamental criteria of blasting engineering.
