Description

[0002] The ventilation conditions underground in coal mines are directly related to the safety and work efficiency of miners. Insufficient ventilation or abnormal wind speed may lead to the accumulation of harmful gases such as gas, increasing the risk of accidents.

[0003] Traditional wind measurement methods require workers to carry handheld wind measuring equipment underground in coal mines for on-site measurements. This not only increases labor costs, but also poses significant safety risks to workers working in cramped, dark, and damp conditions, posing a significant threat to their physical and mental health. Furthermore, when ventilation is insufficient, gas concentrations can rise rapidly, often undetectable by monitoring personnel.

Furthermore, poor coordination between the two devices prevents remote data transmission and real-time monitoring, making it difficult to meet the high standards of ventilation monitoring required by modern coal mines. Furthermore, measurements of roadway ventilation pressure are susceptible to atmospheric pressure fluctuations, leading to errors between data measured at different times, further exacerbating safety risks.
