The optimization of the blasting process is essential in mining operations, since the degree of rock fragmentation that will be obtained depends on this process, which, being optimal, generates efficiency and cost savings in the following unit operations, a bad blast it can cause lower productivity of hauling equipment, bank formation, low productivity in crushing, among others. The main objective of the present study is to improve the fragmentation of the rock mass through the use of electronic detonators, thus optimizing the unitary blasting operation. The thesis is developed in four chapters that contain: The first deals with the statement of the problem in which the generalities, the description of the problem, the objectives and the background are detailed; the second chapter explains the blasting process, the detonation, the initiation systems to finally explain the electronic detonators in more detail; the third chapter details the development of the research work, from the initial data collection to the analysis of the results obtained, it also details the results of the tests with electronic detonators; and the fourth chapter shows an analysis of the results obtained, making a comparison with the baseline surveyed. At the end of the study, it was concluded that the use of electronic detonators improves the fragmentation of the rock mass by 18%.
