Annotation: In the article there are given the results of studying the processes of physical wear of building structures of sloping head-frames. The main types of aggressive influences are corrosion and abrasion media; mechanical influences, such as impulses and impacts; operational imperfections. For head-frame structures, there have been fixed three operational zones, all of them being homogeneous by the composition and aggressive media intensity. Four basic stages of physical wear have been determined and their dangerous states have been classified. There have been also stated principles of reinforcing for different stages of physical wear. The cross-section losses of constructive elements being up to 30%, the latter can be reinforced by the built-up method. The cross-section losses of constructive elements more than 30%, head-frame structures, it’s a good idea to reinforce head-frames by internal and external duplication of basic carrying structures. While reinforcing the structures of head-frame beds installed on the fangs, air-tightness should be taken into account. A rational constructive form of the head-frame bed structures are laminated structures reinforced by stiffening ribs located on the outside.
Keywords: sloping head-frames; aggressive influences; physical wear; reinforcement of building structures.
