[en] The results of rock blasting in terms of fragmentation and generated vibrations depend strongly on the behaviour of rock materials and type of explosives, but also on the sequence of blasting. (...) This paper presents the experimental conditions implemented (type of explosives, blasting pattern, number of holes, geological conditions, mechanical behaviour) and the overall results obtained, specially after the Fourier's transform treatment and the use of spatial functions to understand the effect in different directions.
