Abstract. Theoretical considerations and results of numerical computations regarding a slender column modeling mining supporting structure were presented in this paper. The system was subjected to a selected case of a specific load (follower force directed towards the positive pole), active and passive. The numerical simulations presented in this article refer to the influence of a cross-section variable along the axis and the geometry of a structure implementing an external load on the value of critical force.
