These pillars can be up to 40% of the total coal in the seam although this coal can sometimes be recovered at a later stage. This can be achieved in what is

2019-4-30  Coal is formed when dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal. The harder forms of coal, such as anthracite, are metamorphic rocks, which means they were changed by very high temperature and pressure. Coal is a fossil fuel and can be burned for energy or heat.
