The paper presents the results of studies of technical solutions proposed in Kuzbass State Technical University and implemented in auger drilling equipment, characterized by the presence of a cyclic feed of a boring machine on the face and the corresponding reverse of the work by hydraulic jacks. Operation of complexes, which design feature is to provide a common plane for the axis of the boring hole and vectors of axial forces of the auger feeding mechanisms, was researched. The stress state of the cyclic step-feeding mechanism’s functional elements by mathematical and software means of the finite element analysis is considered. The threshold values of the feed forces are determined from the point of view of ensuring the safety margin of welded joints used in the cyclic step-feeding mechanism’s structure, and from the point of operational reliability of the system as a whole. The obtained data allowed making recommendations for further improvement for the subsystem of the auger’s cyclic step-feeding mechanism.
