- Abstract
As an objective necessity of restricting the scope of the metal support used nowadays to the implementation of the current underground mining works resulting from the mismatch of symmetrical construction support system with maximum expression vector uneven pressure, as well as economic reasons, generated by higher metal costs and workmanship registered for machining and acquisition rolled sections by applying the additional treatment provider and improving the quality improvement becomes increasingly necessary to introduce and generalize submissions anchored to strengthen the rocks. Given the beneficial contribution of anchored support in strengthening and increasing the rock resistance to shear and tensile forces with training and involvement in taking requests consolidated area very shortly after the execution of excavations, the paper analyzes the conditions of sedimentary rocks of Jiu Valley the possibility of introducing and generalization of anchor process fixation rods based on the principle of friction in the surrounding rock of Split Set and Swellex types, which have seen lately a wide range of distribution in various other sectors of construction for fixation and consolidation of rock massifs .
