Digging
deep mining is how coal removed
Coal is removed from deep underground through a process called underground mining. This involves digging shafts into the ground, then using machinery to extract the coal from the coal seam. Miners then transport the coal to the surface for processing and distribution.
Oil can be extracted much easier than coal because it is a liquid. Once the oil reservoir is tapped, it can be removed relatively easily, whereas coal must be physically removed at every extraction.
Coal still in the ground is called "coal reserves".
Coal that is still in the ground is referred to as coal seam or coal deposit.
