[0037] Referring to Figures 2 to 4 , the method for connecting the first end and the tail end of the diamond rope saw by using the above underground unmanned rope connecting device comprises the following steps:

[0038] 1) complete the mining area operation roadway excavation, including the adjacent upper roadway 34 and lower roadway 39; in the upper roadway 34, drill hole operation is carried out, the drill hole depth is to penetrate the interlayer 38 between the adjacent upper roadway 34 and lower roadway 39, to obtain two independent through holes, respectively referred to as through hole I 36 and through hole II 33.

[0039] The thickness of the interlayer 38 between the adjacent upper roadway 34 and lower roadway 39 is limited according to the specific conditions of the ore vein and the mining area, and is different from tens of meters to dozens of meters deep.

[0041] Considering that the weight of the diamond wire saw itself is too large, in order to prevent the device from separating the magnet 31 from the iron block 37 when the iron block 37 is pulled to the upper roadway 34, it is best to first bind the pull rope 35 at one end of the diamond wire saw, fix an iron block 37 at the end of the pull rope 35, and lower a part of the pull rope 35 so that the iron block 37 on it enters the lower roadway 39. In this way, after that, the device pulls the iron block 37 to the upper roadway 34, and the weight borne by the magnet 31 and the iron block 37 after being attracted is only the weight of the pull rope 35, which eliminates the phenomenon of separation of the magnet 31 and the iron block 37.

[0042] 3) lower the steel wire rope 5, and use the steel wire rope 5 to drive the above-mentioned underground unmanned rope connection device into the through hole II 33, and ensure that the bending mechanism in the underground unmanned rope connection device enters the lower roadway 39 according to the feedback of the lamp camera 28 in the underground unmanned rope connection device.

[0043] 4) control the fixing mechanism to make the compression spring 15 in the fixing mechanism in a compressed state through the operation of the control system, so that the underground unmanned rope connection device is fixed in the through hole II 33, as shown in Figure 2

[0044] 5) control the rotating mechanism to make the bending direction of the telescopic arm connected with the bending mechanism be the direction capable of contacting the iron block 37 below the through hole I under the feedback of the lamp camera 28 through the operation of the control system.

[0045] 6) first operate the control system to control the telescopic arm to move to an appropriate length, and then operate the control system to bend the bending mechanism upward until the magnet 31 on the telescopic arm is attracted to the iron block 37 below the through hole I 36 under the feedback of the lamp camera 28 through the operation of the control system, as shown in Figure 3 ​The bending mechanism is controlled again to move in the opposite direction to the previous bending direction until the telescopic arm is parallel to the base plate 1, as shown in Fig. 3c. Figure 4

[0046] 7) By operating the control system, the fixing mechanism is controlled to make the compression spring 15 in the released state, so that the downhole unmanned rope connection device can move up and down in the through hole II 33.

[0047] 8) Pull the steel wire rope 5, and pull the traction rope 35 up to the upper roadway 34 by the downhole unmanned rope connection device driven by the steel wire rope 5, and the staff completes the connection of the two ends of the diamond wire saw in the upper roadway 34.
