This research proposes the application of a Comprehensive Blasting Model to optimize blasting processes in underground mining units. This model consists of six steps. Firstly, the information gathering process, which records rock mass data, reports of blasting, fragmentation, etc.; second, thermodynamic criteria, for the selection of explosives. Third, algorithms of Roger Holmberg and Peter Calder, for the design of controlled drilling and blasting mesh, respectively; fourth, use of the JkSimblast blasting simulation program, in which the obtained perforation mesh will be simulated. Fifth, field tests, in which the simulation obtained in the previous step will be used and will be implemented in the field. Finally, the statistical evaluation of our model using Cronbach's Alpha coefficient, which will measure the reliability of the five processes, through the correlation of the steps described. This model was verified in the Santa Luisa Mining Company, Huanzalá Unit, with the following results: the levels of overbreaking were reduced from 14 to 7%; regarding fragmentation, the P80 was decreased to 7.71 inches. The blast damage indicator (BDI) decreased in value from 1.03 to 0.87. Also, the load factor and power factor decreased by 24% and 43.18%, respectively. Lastly, excavation costs were reduced from $399.49 to $374.15 per meter of advance.
