[0002] Coal gas leakage detection refers to the real-time monitoring and detection of coal gas (mainly methane) leakage in the environment through various technical means and equipment. This detection is usually used to prevent explosions, fires or poisoning accidents caused by gas leakage in coal mines, coal storage yards, coal transportation and processing. In the prior art, it is usually detected whether coal gas is leaking by having the inspector apply soapy liquid on the outside of the pipeline to observe whether bubbles are generated. However, since the manual application of soapy liquid on the pipeline is inefficient, the operation is inconvenient, and it is easy to be incompletely applied, resulting in low detection accuracy.
