The researches data of stress and strain system «rock massif – support» during development of thin coal seams are given and the possibility of metal consumption decrease for frame-anchor support on the basis of computer modeling for different structure of coal containing strata is substantiated. As well comparison of two types of frame-anchor support are made according to pressure and movement components for frame support SIP-27, that will allow to optimize metal consumption of the frames and the labor input for their erection.
