What function do CH4 monitors serve on a shearer?

CH4 monitors serve the vital function of monitoring methane concentrations on a shearer. Methane is a flammable gas that can accumulate in underground mining environments, posing significant safety risks such as explosions or fires. The CH4 monitors are designed to detect the levels of methane present in the atmosphere around the shearer to ensure a safe working environment.

By continuously tracking methane concentrations, the monitors provide real-time data that allows miners to take necessary precautions, such as increasing ventilation or halting operations if dangerous levels are reached. This proactive approach to managing gas levels is crucial in maintaining the safety of operations and protecting the health of workers. Understanding the critical role of CH4 monitors highlights their importance in risk management within the mining industry.
