Abstract

Loading on support is defined by geomechanical, technological and geometrical parametres. At комбайновой technologies of carrying out of developments loading decreases in 1,5-1,6 times. Rigid dependence of size of loading on quality of filling закрепного spaces remains. Bearing ability of arches from СВП-27 and СВП-33 exceeds bearing ability of arches from СВП-22 accordingly on 33 and 76 %. Bearing ability of an arch with the account of plastic deformations of a steel increases on 32-42 % in comparison with elastic calculation.
