Abstract: Discontinuities are one of the factor causing the reduction of the resistance of the rocks to the destruction to the explosive. Nevertheless, the distance between the cracks their slope and the position of the detonator play a significant role as for the final result of the fragmentation of the rock. In our investigation, to study the phenomenon of the destruction of the rocks to the explosive and to determine the role of the factors quoted previously, we prepared models starting from the limestone rock. The results of the tests show a perfect correlation with the results obtained under the conditions of the mines of Algeria and those establish by Kouznitsov-Ramler.
