Coal Miners begin by boring out a pocket of space in the hill, mountain, etc, where the coal strike is. With the use of dynamite, they enlarge the pocket of space into a tunnel that extends the length of the vein.
As they go further into the mountain, hill, etc, they lay railroad tracks and use small coal trains to move inside, so they can fill the cars, and bring it out.
By the use of coal chutes, and sledge hammers, and picks, they break the big chunks of coal into little chunks of coal and drop them into the rail cars.
Inside the mountain, they use battery powered lights on their helmets, and use air driven tools to mine, so that it doesn't burn and cause a fire.

As it's found underground, it has to be mined. Coal seems to be what's left from ancient organic materials after it's been compressed and heated deep in the earth. If the materials haven't been cooked long and hard enough, they look more like the original organics - this material is 'soft' coal, lignite or even peat. Peat still contains the structures of leaves and branches and you can see it's origins.
