Influence of the technogenic weakened zones in containing breeds which are created round mountain developments at the big sizes long well fields, on a way movement of the high-efficiency mechanised clearing complex is considered. Laws of influence of imposing of a stationary zone of basic pressure from conveyor and a dynamical zone of a clearing face on formation of the is intense-deformed condition of a file are resulted at crossing by mountain works of the technogenic weakened zone. Value of width and an arrangement pillar which is formed in the course of approach of a clearing face to incline, on lowering of breeds in working space and stratification of the basic and direct roof is established.
