What are the dangers in an underground coal mine?
• Supplies can be cut off. • Communication can go down. • There might be some confusion. • Bad air begins to build up, especially if there is a fire. For further discussion, the students can be encouraged to think of ways safety can be improved in underground coal mining. As an example, if there were a better way to communicate with the trapped miners, their location might have been ascertained sooner and hence a better rescue plan might have been devised.
