ABSTRACT
One of the perspective types of anchor support are tubular anchors, installed with the help of energy obtained by detonating an explosive charge. They are relatively cheap to manufacture and install and have good support characteristics. However, the basic difficulty restraining wide implementation of tubular anchors lies in the fact that the process of interaction of tubular anchors with rock surface in the borehole is not studied enough and is not fully described by mathematical equations and hence proper methods of calculating basic parameters of support are not available. So, studying the process of interaction of forces in the system “tubular anchor-rock”, creating on this basis an engineering method of calculating tubular anchor parameters and improving construction and technology of their installation are the actual tasks for theoreticians and practitioners constructing underground workings with the aim of increasing their stability.
