The tendency to use explosive of great power makes that it is also a necessity the application of new techniques to design the drilling patterns, because is necessary to know the use of the relative bulk strength (RBS) in the present investigation. This theory has it{s base in that the energy of an explosive compared to each other is very different, in the same hole volume, that is why changing in a mine operation, an explosive in use for another of more energy has to keep in mind the difference about the energy of each explosive. This approach also implies that the use of the energy factor should be a daily factor instead of the use of the load factor or power factor, which is used in most of the mining units of our country however the energy factor has many years of validity in the developed countries up to date because it allows to quantify the yield of the energy of the explosive correctly. The RBS allows to modify the original dimensions of the burden (B) and spacing (S) quickly and in this way it allows us to save time and cost in the test rehearsals and error for the implementation of the new dimensions in the field. In the work is carried out a change from ANFO to heavy Anfo 50/50 and it was determined that it can decrease the drilling and blasting costs with a more energetic explosive, as well as it improved the fragmentation obtained using ANFO.
