Abstract. The established control regularities of condition mine workings support system in the zone of influence stope working on the basis of controlling displacement processes of end-anchored marginal rock and loading frame-bolting support by means of choosing resource-saving regime of anchors working constant resistance are defended. The complex calculated expressions by forecasting all components of load intensity diagram, along of the mine working contour have been derived. The researches for determination the internal forces in the frame depending on its size, component of load intensity diagram and anchors installation parameters were carried out. A correlation constraint rational parameters of anchors installations with geological and mining conditions supporting mine working in the stope influence zone are derived. The revealed regularities are the basis for an engineering method of calculation of resource-saving parameters frame-bolting support. The mine researches established stability regularity of reduce roof and floor convergence mine working by 25-33%, and sides by 54-65% that reduced cross-section loss in the zone of abutment pressure by 26,5-37,0%. For improving stability of mine workings confirmed the feasibility of the developed recommendations on differential strengthening frame support by anchors with adjustable force deformation characteristic.
