The answer to I come from a mine and get surrounded by wood is coal. Coal is formed when ancient plant matter gets buried in sedimentary rocks and then subjected to intense pressure and heat over millions of years. It is typically found in underground mines, where it can be retrieved through mining operations. Once the coal has been mined, it often gets transported to nearby power plants or other industries that use coal as an energy source, which creates a surrounding of woody biomass around the area due to burning off the excess material.
