CONVEYING METHOD BY STRETCHED BELT CONVEYER, AND STRETCHED BELT CONVEYER FACILITY

摘要

PROBLEM TO BE SOLVED: To efficiently convey muck drilled in a plurality of places in a small occupied volume. SOLUTION: The stretched belt conveyer facility is disposed in a tunnel 1 drilled by a bench cut construction method and conveys out a precedent much generated by drilling a working face and a following muck generated by drilling a lower bench 5 with a single stretched belt conveyer 11. The precedent muck is discharged to a muck merging hopper via an intermediate tripper disposed on the way of a carrier belt 21 at a muck merging part 11C, the following muck is conveyed into the muck merging hopper by a following muck throwing conveyer 13 to be made to merge with the precedent muck, and the merged muck is fed onto the carrier belt 21 by a vibration feeder by a suitable amount.
