METHOD AND DEVICE FOR REMOVAL OF OVERBURDEN IN COURSE OF TUNNEL DEVELOPMENT

摘要

FIELD: mining.;SUBSTANCE: in course of open pit development or advancing face with ground support, a first opening made in pipe-shell of an auger conveyor in the direction of removal is opened, and a second opening located behind the first opening in the direction of removal and made in the cross-section of the pipe-shell of the auger conveyor is closed. When advancing a face with a hydraulic weight, the first opening is closed, and the second opening is opened. Device for overburden removal in tunnel-driving machine with at least one auger conveyor, wherein said or each auger conveyor is surrounded by a housing, with a first opening formed in the housing from the side of the stope, with the second opening formed in the housing at a distance from the stope, with configured with the possibility of selective actuation by a first gate for the first opening and configured with the possibility of selective actuation by the second gate, which passes through the housing and is designed for hydro-mechanical separation of the first section and the second section of the auger conveyor or an auger conveyors system. At that, the first opening ends in the unloading device for advancing a face with ground weight, and the second opening ends in the unloading device for advancing a face with hydraulic weight.;EFFECT: development of method and device for removal of overburden in course tunnel development when switching between faces with ground weight or open development and advancing face with hydraulic weight, which would provide for low sensitivity to interferences with insignificant wear during the operation.;6 cl, 9 dwg
