PROBLEM TO BE SOLVED: To provide a drilling material transporting method and device, which can shorten a tunnel excavation period.SOLUTION: In a transporting technique to transport mucks generated by excavating a face K of a tunnel T by blasting to a mine mouth side of the tunnel, a conveyor 2 for transporting the mucks is disposed on a front stage of a crusher 3 that crushes the mucks. The conveyor is disposed at a position away from the face in a state where a first conveyor 2a and a second conveyor 2b of the conveyor 2 are made into double layer structure when blasting, while the second conveyor is moved to a position closer to the face than the first conveyor so that the mucks can be stocked on the front stage of the crusher when transporting the mucks after blasting. Thus, even in the middle of the muck crushing by the crusher, supporting of the tunnel inner wall face near the face can be started at a stage where work space is ensured around the face by loading the mucks around the face on the conveyor. Therefore, tunnel drilling speed can be increased and a tunnel excavation period can be shortened.SELECTED DRAWING: Figure 2 |
