Example Embodiment
[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 det...
