THE OPPORTUNITY OF IMPLEMENTATION THE ANCHORED SUPPORTING OF UNDERGROUND EXCAVATIONS

Abstract

As an objective necessity of restriction the scope of the steel timbering used for the current metalsupport of the underground excavations, resulting from the not correlation of the symmetric constructionsupporting system with uneven maximum vector manifestation of pressure, as well as economic considerations,generated by the high costs and labor for the lamination of metal profiles, by applying to the supplier aadditional treatments improve, it becomes increasingly necessary to introduce and generalization on how toconsolidate rocks by anchored support. The paper analyzes the possibility of generalization the anchoredsupport for underground excavations, as well as the specific features of this support system in its interactionwith the surrounding rock, with the aim of making the option for choosing this method of consolidation therocks.
