In recent years, mining has faced a gradual decrease in the metal´s prices, generating a reduction in the profitability of the business as a result of lower mineral reserves. This has led to the adoption of operational schemes focused on the continuous improvement of each of the processes within the mining cycle, in order to reduce costs. For this reason, it is necessary to visualize each of the activities involved, such as drilling and blasting, which have a productive and economic impact on the global process. Consequently, this research focuses on optimizing rock fragmentation, through a drill and blast mesh design, by integrating the engineering concepts of blasting and characterization of the rock mass. For this, the Pearse mathematical model will be applied, in order to calculate the controllable parameters of the design and obtain the expected results. Likewise, the scope of the work includes the analysis of the productivity of the mining cycle, as well as the quantification of the impact of the proposal in terms of costs. It begins with the baseline analysis, which consists of measuring the results of current P&V mesh designs, in order to determine the variables that are generating coarse rock fragmentation. Subsequently, the mesh design proposal is proposed considering the greater amount of data and information from the Tacaza pit. Then the field work is carried out, consisting of the monitoring and control of activities, in order to comply with the designed parameters. Finally, the fragmentation results are measured in the Wipfrag software, and the productivity and costs in the mining cycle are analyzed. From the results, an improvement in fragmentation is obtained, since it is possible to reduce the diameter of rocks from 13.0 to 5.0 inches on average. This leads to an increase in the effective performance of the equipment and a cost reduction of approximately US $ 9,600 per month. These new measures generate added value for the company, through a sustainable mining operation, which seeks to make the business profitable from a holistic view of the process.
