Z is guided to the portion related to the upstream end of the continuous belt conveyor 1 by the first hopper 3.
[0029]
Then, the slip Z relating to the face K guided by the first hopper 3 is continuously conveyed without spilling from the portion related to the upstream end of the continuous belt conveyor 1 to the pit P of the wellhead.
[0030]
Then, when all of the gap Z discharged from the face K due to blasting is discharged to the pit P at the wellhead, the discharge of the gap Z related to the face K is completed.
[0031]
(2) Discharge of the slip Z according to the invert I Next, when all of the slip Z discharged from the face K due to blasting passes through the middle portion of the continuous belt conveyor 1 where the slip Z according to the invert I should be discharged, The discharge of the slip Z relating to Invert I is started.
[0032]
That is, when the slip Z related to the invert I scraped by the trencher 21 is introduced into the second hopper 4 by the discharge conveyor 21a in the middle part of the mine, the slip Z related to the invert I is transferred to the second hopper 4 Thus, the belt is guided to an intermediate portion other than the portion related to the upstream end of the continuous belt conveyor 1 and continuously conveyed from the intermediate portion to the pit P at the wellhead.
[0033]
At this time, on the other hand, when the position of the downstream end of the discharge conveyor 21a fluctuates due to the scraping work of the trencher 21 toward the face K, the travel control of the traveling carriage 31 using the sensor and the lift bracket in the lifting device 32 are performed. The control of the horizontal motion and the vertical motion 32b is performed in real time.
[0034]
Thereby, the traveling of the traveling carriage 31 corresponding to the movement of the trencher 21 and the horizontal and vertical movements of the lift bracket 32b are continuously performed, and the approximate center of the upper opening 42a of the second hopper 4 is downstream of the discharge conveyor 21a.

The horizontal movement and vertical movement of the bracket 32b are performed in real time.
[0036]
Thereby, the traveling of the traveling carriage 31 corresponding to the position of the rubber belt 1b of the continuous belt conveyor 1 and the horizontal operation and vertical operation of the lift bracket 32b are continuously performed, and the lower opening 42b of the second hopper 4 is formed in the continuous belt conveyor. It will be maintained so as to match the center of one rubber belt 1b.
[0037]
It should be noted that the traveling control of the traveling cart 31 corresponding to the movement of the trencher 21 and the operation control of the lifting device 32, the traveling control of the traveling cart 31 corresponding to the position of the rubber belt 1b of the continuous belt conveyor 1, and the lifting device 32 The operation control is performed in a superimposed manner.
[0038]
The discharge of the slip Z related to the invert I is completed when all of the planned slip Z for the scraping work by the trencher 21 is discharged to the pit P at the wellhead.
[0039]
In the present embodiment, from the viewpoint of preventing the spillage of the slip Z from the continuous belt conveyor 1, the discharge of the slip Z related to the face K and the discharge of the slip Z related to the invert I are not performed at the same time. However, it is not limited to this. That is, it is possible to simultaneously perform the discharge of the slip Z related to the face K and the discharge of the shift Z related to the invert I as long as no slippage of the slip Z from the continuous belt conveyor 1 occurs.
[0040]
