The mining and burning of coal is the most damaging to the environment.
The miners would dig a hole and put any mining tools they needed to get the coal out. but no not all the coal was removed.
In the early years of coal mining, primitive production methods meant individual workers owned and operated their own tools and were paid piece-wages, according to the amount of coal mined.
Coal has only one advantage relative to oil, which is that it is abundant and relatively inexpensive. Disadvantages include, it is more polluting (due to impurities in the coal) and it is harder to handle; oil can be pumped, whereas coal has to be shoveled. Coal mining is often more difficult and dangerous than pumping oil out of the ground. Coal dust creates the dangers of explosion, and black lung disease.
