Summary:The longwall mining method is widely used all over the world. Underground coal mining has improved both from production and productivity with the development of the mechanized longwall mining method, but there are still certain risks that can result in unacceptable levels of safety. When there are multi-layers of coal seams, one of the most dangerous issues is the pressure-relieved gas from the adjacent coal seams, which may cause a gas explosion.
