dc.description.abstractAfter digging a mining structure in a rock mass, a redistribution of stresses occurs around this mining structure. During this redistribution, the rocks tend towards a new equilibrium state and undergo certain deformations, which can become dangerous during the mine exploitation, or even turn into a major accident. Therefore, the study of stability in fractured rock masses, as well as the modelling of mining structures, requires a detailed description of the behavioural models and their mechanical properties. These mechanical properties are influenced by scale effects, or even depend on the volume considered. The objective of this article is to study the influence of the effect of the shape and the load applied in order to approve the evaluation of the characteristic values of the mechanical properties of the excavated rock masses. Even to pinpoint the probability of a rupture in a perspective sizing of works and management of risks associated with the exploitation of mining resources (mines, quarries, drilling, etc.). The evaluation of the characteristic resistance of a pillar will be the main object of our research work. As a case study, we have taken the case of the Chaabet El Hamra underground mine in the city of Setif, Algeria.
