The invention provides a method for side air supply of a driving face of a large-
diameter deep vertical shaft. According to the method for side air supply of the driving face of the large-
diameter deep vertical shaft, for a high-temperature driving face of a deep vertical shaft with the
diameter larger than ten meters, a vertical flexible air duct is connected with a traditional vertical main air supply duct and a four-way main air inlet
pipe fixed to the bottom side of a last-layer hanging
scaffold, transverse flexible air ducts are connected with
branch air inlet pipes of a four-way device and guiding air inlet pipes installed at the bottom of the last-layer hanging
scaffold, and then
fresh air flow can be directly supplied to the driving face located below the last-layer hanging
scaffold. The guiding air inlet pipes are installed on the lower side of the last-layer handing scaffold through a suspender, both the air supply angle and the air supply height of each guiding air inlet
pipe can be adjusted, so that air can be supplied to different areas of the driving face, and the functions of vertical ventilation and dust removal are also achieved. By the adoption of the method for side air supply of the driving face of the large-diameter deep vertical shaft, most areas of the driving face are located on the
fresh air flow side, the occupied area of the flexible air ducts and the guiding air inlet pipes is small, normal driving construction of the vertical shaft is not influenced, additional arrangement of a
tail-end draught fan is not needed, multiple-angle side air supply with multiple air inlet pipes can be achieved through the air pressure of a main ventilation fan, and the thermal environment of the high-temperature driving face of the deep vertical shaft is remarkably improved.
