CONVEYOR DEVICE FOR LAYER-BY-LAYER PRODUCTION OF MATERIAL IN OPEN MINES, AND METHOD OF COORDINATION OF CONVEYOR DEVICE WITH METHODS OF PROGRESSIVE DEVELOPMENT

摘要

FIELD: machine building.SUBSTANCE: conveyor device has head unit and tail unit (3), at that the head unit is divided to mobile head drum unit (2), and fixed transfer unit (1). Determined by development change of distance of the belt conveyor between the tail unit and transfer unit is compensated in accordance with the invention by change of distance between the mobile head drum unit and transfer unit.EFFECT: coordination of the conveyor unit with depth of development without cut of the conveyor belt.5 cl, 2 dwg
