Coalbed methane containing methane is often associated with coal mines. What safety measures do you think should be taken in coal mines? Where and what kind of safety signs should be posted?

The first step to control gas (coalbed methane) in coal mines is to provide good ventilation facilities in the mining area to prevent gas concentration from gathering. Second, do a good job in three preventions including fire prevention, explosion prevention, anti-static and leakage prevention. Third, standardize management and study safety education seriously. The fourth is to cooperate with companies that have the ability to mine coal bed methane to develop coal bed methane and turn waste into treasure to realize the national new energy utilization.

As for the safety signs, they include: no fireworks, no static electricity, no chemical fiber clothing, wearing a helmet, high gas area, safe electricity use, safe production, dangerous zone, etc. These safety signs should be posted in conspicuous places where workers commute to and from work.
