The evaluation of the flat slab fasteners used at the Yakovlevsky mine structures is given. Designs and standard sizes of elements, rational zone of action of the support, application interfaces are determined. The expediency of the use of the support with an arched overlap, which has a greater load-bearing capacity and operational reliability, is substantiated.
