Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
Coalmining safety is a reflection of coalmining risk and its unique chemical–physical properties as a carbonaceous mineral. Risk has several meanings that are important to coal safety. Risk is both a perception held by every person who works in the industry and a technical concept open to qualitative and quantitative assessment.
