Essay

The laws of cavity-formatione in walls of a chink are established and the passport-technological simulation modeling of the design circuit of the system "working face of shaft - pilot hole" is made. The parity(ratio) of the average size of a piece to pass of breed and diameter of a chink is determined, the interrelations between parameters deformation of breeds fractional composition of received mined rock skipped on pilot hole are determinated. The economic efficiency of the designed technology is estimated. The criterion of a choice of an optimum diameter of a chink is given. The new way shaft of vertical mine excavations is developed.
