What is the principal gas found in coal?

Explanation:
Methane is the principal gas found in coal. Gases get trapped in the tiny pores of coal as it forms, and the most abundant one is methane, which is why coal seams are described as containing coalbed methane. Other gases like carbon dioxide, nitrogen, and oxygen can be present, but they are typically much less abundant than methane. This is why methane is the key gas miners monitor and manage for safety.
