Method for side air supply of driving face of large-diameter deep vertical shaft

[0017] An embodiment of the present invention will be further described below in conjunction with the accompanying drawings:

[0018] The method for air supply on the side of the driving face of a large-diameter deep shaft of the present invention includes providing an air supply tube passing through one side of the multi-layer suspension plate in the vertical shaft. The air supply tube includes a main air supply tube 1 and a vertical flexible air tube 2 connected sequentially. , Vertical flexible air duct hole 3. With the continuous increase of shaft excavation depth, the ambient temperature of the excavation face gradually rises. Firstly, three induction ducts 8, 9, 10 are fixed to the bottom of the suspension pan 5 of the last layer through the bracket 7 and near the main air supply cylinder hole 4. The air outlet pipes 8, 9, 10 are detachable and adjustable in angle, which can realize different horizontal and vertical air supply according to actual needs; the bracket 7 is detachable and can be moved vertically, which can realize the induction air outlet pipe 8, 9, 10 Air supply to different heights. Use three horizontal flexible air ducts 6 of the same length to connect the three induction ducts 8, 9, 10 in parallel to the three branch ducts 12, 13, 14 of the four-way 11 along the horizontal direction of the bottom of the last layer of the suspension plate 5; According to actual needs, the number of four-way 11 branch duct ducts 12, 13, 14 and induction ducts 8, 9, 10 can be adjusted. The three sections of horizontal flexible air duct 6 are respectively connected by flanges to the induced air outlet pipes 8, 9, 10 and the four-way branch air outlet pipes 12, 13, and 14. In order to ensure the resistance balance and uniform air volume, the three-section flexible air duct The length is equal. The main air inlet of the four-way 11 adopts the vertical flexible air duct 2 to connect to the main air supply duct 1 along the vertical flexible air duct hole 3, so that the fresh air flow can be sent to the deep shaft from the side of the induction duct 8, 9, 10 The side air supply mode of the face. The vertical flexible air cylinder 2 is connected with the main air supply cylinder 1 by a flange, which facilitates the disassembly and assembly of the multi-layer suspension plate when it is moved.

[0019] In addition, when the air supply angle of the induction ducts 8, 9, 10 is adjusted to the vertical direction, the lateral air supply mode is changed to the vertical air supply mode, and the dust removal function of conventional ventilation can also be realized.
