[0002] The extraction of combustible gas refers to the measures of using special equipment to extract or discharge the combustible gas in coal seams, rock formations and goafs and collect and utilize it. There are various methods for strengthening the extraction of coal seam gas, such as high-pressure and medium-pressure water injection into coal seams, hydraulic fracturing, hydraulic slotting, loose blasting, large-diameter (reaming) drilling, grid-like dense hole layout, pre-splitting controlled blasting, cross-hole layout, etc. Among these methods, most methods have achieved the effect of increasing the gas drainage volume in the test area.

[0003] The "gas drainage hole sealing device" disclosed in the patent publication number "CN220267658U" includes a storage pipe body and a taking mechanism. The storage pipe body includes a main pipe body and a sleeve. A first chuck and a second chuck are arranged inside the main pipe body. A filter screen is arranged on the surface of the first chuck, and a filter screen is also arranged on the surface of the second chuck. The adjacent filter screens are arranged correspondingly. The taking mechanism includes a fixing plate, a wear-resistant cushion layer and a diversion pipe. An airbag is installed between adjacent fixing plates. The operator inserts the main pipe body area into the drilling hole, and the sleeve supports the main pipe body. The operator can draw the external gas into the sleeve through the arranged diversion pipe, and filter the gas step by step through the filter screens on the first chuck and the second chuck. At the same time, the operator can pressurize the airbag to make the airbag expand. The airbag gradually fits on the wear-resistant cushion layer and pushes the wear-resistant cushion layer to fit with the inner wall of the drilling hole, avoiding air leakage of the inflatable structure, reducing the sealing hidden danger of gas extraction, and ensuring the gas extraction effect.
