Research on the Application of Photoacoustic Spectroscopy Technology in Real-Time Monitoring of Multi-Component Gases in Mine Gas

In contemporary times, the safety of mine operations has emerged as a matter of paramount importance. The multi-component gases present in mine gas,whitch include flammable and explosive gases, pose substantial hazards to human health.As a result, the real-time monitoring of multi-component gases in mines is of critical significance. Existing technologies are plagued by numerous drawbacks, such as low sensitivity, susceptibility to interference from other gases, sluggish response times, and exorbitant maintenance costs. Conversely, photoacoustic spectroscopy (PAS) presents distinct advantages, including high sensitivity, strong selectivity, and low maintenance expenses. Photoacoustic spectroscopy is a technique that converts optical signals into acoustic signals, thereby offering a novel technological avenue for the early warning and prevention of mine gas disasters. However, photoacoustic spectroscopy also has limitations, primarily in terms of detection range and stability. The employment of high-precision optical components can further optimize photoacoustic spectroscopy technology.
