This thesis deals with improving fragmentation in an iron mine with the use of gasified emulsion. To get an improvement, different scenarios and the main variables that intervene in the result of fragmentation were analyzed. For this, I reviewed some books, technical works from other mines and recommendations from our blasting accessory suppliers, determining the strong impact that the use of gasified emulsion would have. Work was done to improve the fragmentation of iron ore by applying blasting theories in the increase of the detonation pressure delivered by the explosive directly related to the higher detonation speed of the gasified emulsion compared to the matrix emulsion, modification of the start sequence and times between rows, electronic delays and change of perforation meshes. The improvements in the blasting result are a combination of the controllable variables (design parameters), for the present study emphasis was placed on the higher VOD (Detonation Velocity) that the gasified emulsion could deliver, however, they were also made modifications of other variables, such as the starting sequence, use of electronic detonators and others that will be detailed in the development of the thesis.
