[0002] Oil and Gas Coal Seam Methane Extraction Shafts are facilities used to extract natural gas (coal bed methane) and oil from underground coal seams. Such shafts are usually located above ground and extend through wellbores to underground coal seams. During the coal bed methane and oil extraction process, extraction shafts are used to inject compressed air or liquids to increase underground pressure and facilitate the release and extraction of coal bed methane and oil. In addition, extraction shafts can also be used to monitor the production and quality of underground gas and liquids and support the operation and maintenance of underground equipment. Such facilities play a vital role in the oil and gas industry, helping to improve energy extraction efficiency and production.

[0003] In the prior art, most mining shaft pipes are one-piece pipes, which are not convenient for disassembly and splicing, resulting in the inability to replace the pipes when they are damaged. Some mining shaft pipes are spliced ​​by welding, which makes it inconvenient to splice the pipes during the mining process. When the pipes are not long enough, they cannot be spliced ​​quickly, and the drill cannot be disassembled and cleaned. After mining, the drill is easily sticky with mud and dust, which affects the mining effect and work efficiency.
