[0003] The mining face ventilation equipment in the prior art is mainly flexible air ducts, and most of the assembly forms are in the form of direct hanging, that is, the air duct is directly hung on the slide rail or other equipment above the tunnel. However, this method has significant disadvantages. On the one hand, the directly hung air duct lacks storage equipment, and its effective use length is limited or needs to be advanced with the excavation, which makes it impossible to compress and store the air duct. Combined with the cramped underground construction environment, it causes inconvenience in construction and poor ventilation; on the other hand, based on the fact that the layout length of the air duct needs to be advanced with the excavation, the above-mentioned disadvantages will also lead to poor advancement and deployment of the air duct, especially in the connection work between air ducts, which will cause problems such as inconvenient assembly and cumbersome construction process.

[0006] When storing, the flexible air duct is sleeved on the outside of the flexible air duct storage device and compressed to form an air duct assembly.

[0007] That is to say, the expansion ring serves as a propulsion end, and its expansion ring portion is arranged at the tail end of the propulsion direction, which plays a role in preventing the air cylinder from being excessively released.

[0008] When in use, the following implementation steps are included: Step 1, hang the wind tube assembly on the sliding track above the laneway, the outer surface of the flexible wind tube is arrayed with assembly hanging rings, which are respectively hooked on the sliding track arranged at the top of the laneway, that is, the sliding track is arrayed with sliding trolleys, and the bottom of the sliding trolley is provided with a hanging hook; A long assembly rod is suspended at the lower end of the hanging hook, and the storage section of the flexible air duct is centrally hung on the long assembly rod by the assembly hook on the air duct body; Step 2. When the wind tube assembly described in step 1 is used, one end of the flexible wind tube is connected to the wind-generating device, and the other end is propelled by the flexible wind tube receiving device; the part of the flexible wind tube released from the flexible wind tube receiving device is the releasing section, and the part not released is the receiving section; Step 3. The storage section is gradually advanced in the progressive direction of excavation, and the flexible air tube is gradually released from its tail end during the advancement process to maintain continuous ventilation; at the same time, as the storage section advances forward, the released flexible air tube assembly hooks are gradually separated from the assembly long rod, and the assembly hooks separated from the assembly long rod are sequentially hung on the connecting hooks; Step 4. After the flexible air duct is completely released, the tail end of the flexible air duct on the next-level assembly is directly connected to the end of the flexible air duct on the previous-level assembly, and then pushed forward again as described in steps 1 and 3.

[0009] The beneficial effects of the present invention are as follows: the present invention fills a gap in the prior art, and realizes the compression and storage of the air duct through a simple structure and a clever implementation method; during use, the air duct can be gradually released from the tail end of its storage section, so that ventilation continues while the ventilation port can be advanced along with the excavation position. Based on the above effects, during use, it can cooperate with the supply and return air equipment to perform precise working position positioning for ventilation and dust collection, etc., to ensure ventilation effect and work safety.
