Description

Technical Field

[0001] This invention belongs to the field of underground gas collection and detection technology in coal mines, specifically relating to an inspection and collection device and a collection method. Background Technology

[0002] Coal seam gas drilling is the main method of gas extraction in mines. Since there are thousands of extraction boreholes, dozens of inspection workers are often needed to inspect the gas parameters extracted from the boreholes. Relying on manual inspection has problems such as low data collection frequency and high labor intensity. If mine explosion-proof multi-parameter sensors or electrically controlled valves are installed in each extraction borehole, there are problems such as a huge number of sensors or electrically controlled valves, difficulty in installation, debugging and maintenance, complicated power supply and communication systems, high cost, high risk of explosion failure, and inability to be widely used in underground coal mines.

[0003] In addition, the detection of ambient gases at thousands of fixed points in coal mines is currently carried out manually through fixed-point inspections. Each point often needs to be inspected several times a day, generally requiring dozens of inspection workers, which also presents similar problems as mentioned above.

[0004] To solve the above problems, there is an urgent need for a patrol and data collection device and method that can collect multiple gas parameters through a set of multi-parameter gas detection instruments. It should also have a simple structure, good sealing performance, simple control system, and be suitable for widespread use. Summary of the Invention
