Metal pliable support developmentsin an ore file Yakovlevsky mine

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.

Designing support unilateral rectangular interfase of horizontal developments

The design procedure of loadings on arch support unilateral rectangular interfaces in an ore file of Jakovlevsky deposit КМА is offered. The settlement scheme corresponds rigid and plastic model of deformation of an ore file in a roof of interfaces. A major factor defining size of loading on overlappings of interfaces, emptiness in a roof after filling there are. Low efficiency of flat overlappings of interfaces on chamber frames and advantages of overlappings of interfaces by arches from profile SVP with horizontal couplers from арматурной steels of armature was revealed. Possibility of operative calculation of loadings and a choice of parametres of overlappings on conditions of durability and stability of bearing elements of support in ores of various types is proved.
