“…For example, if rigid and pliable elements interact with each other, then usually in the area of their contact in the pliable element, the significant perturbations of stresses components occur, which often reach the destructive values (Kulczycka, Hałasik, Nowaczek, Whirt, & Szkop, 2017). Therefore, it is a very important issue of matching between the deformation-strength characteristics of the elements included into the fastening system of mine working, against their total adaptation to the nature of rock pressure, conditioned by the action of geome-chanics factors combination (Kovalevska, Barabash, Husiev, & Snihur, 2018;Bondarenko, Kovalevska, Symanovych, Barabash, & Snihur, 2018), including the rigidity of the collapsed rocks and the rocks of immediate and main roof being consolidated in the mined-out space of the longwall face (Kovalevska, Vivcharenko, & Snigur, 2013;Symanovych, Demydov, & Chervatuk, 2013).…”
