In underground coal mining, advancements in technology have enabled the remote monitoring of the atmospheric environment to ensure safety.1
Sensors are deployed throughout the mine to continuously track critical environmental data, including air velocity and the concentrations of various gases. These sensors are integrated with computer hardware and software systems, allowing mine operators to monitor conditions in real time. By providing constant feedback on the mine's atmosphere, these systems help manage ventilation effectively and maintain a safe working environment for personnel.1
