Essay

In the dissertation are proved the parameters of core-concrete fastening of trunks above interfaces . The dominant factors are determined which influence stability of trunks. Is established, that the greatest stability have the trunks with azimuth by a corner of realization of horizontal development 40 … 60 grad. and attitude of width of development to a diameter of a trunk in intervals 0,50... 0,75 and 1,0... 1,2. . Is proved: that cores in a combination with concrete of fix provide stability of a trunk depending on orientation and various depth of their erection. The approaches are proved, is developed and the technology of a structure of vertical sites of trunks above interfaces on air-giving trunk №2 SC "Mine A.F. Zasyadko", that has allowed maximum to increase rates shaft sinking
