Poor ventilation , gas pockets, explosion hazards.

Traditionally a bird was taken into the mine as they are more susceptible to the effects of the contaminants. This is where the phrase "canary in a coal mine" came from.
The gas given out when coal burns is carbon dioxide (CO2).
Because some dumb guy farted and sent a gas rocket that caused the coal to crash down.

Oil , coal, and natural gas
Methane found in coal mines is typically referred to as coal mine methane (CMM). It is a byproduct of coal production and can be a safety hazard due to its flammability and potential for explosions. CMM can also be captured and utilized as a valuable energy source.
