The surface area of the land is less important than the amount of coal to be found. Some mines could have only a very small amount of land at the top, a mineshaft, and many miles of tunnels far underground.
You get 50 mining experience for every coal you mine.
one tenth of Britain's coal came from Wigan's mine

The main use of land at Moe, Victoria, is coal mining. Much of the land surrounding the town is utilised as opencast mines of brown coal in the area.
Will depend on the mine, but in general, underground coal mines may be very wet. One of the first uses of early steam engines was operating mine pumps to control water levels.
They core drill from the surface down and remove samples. These core samples give them the coal seam thickness and coal quality. Multiply the seam thickness by total area and you have the coal reserves, typically measured in acre-feet.

The older power plants used coal, but it polluted so much we try to use other methods.
Sadly unless it us a union mine (there are very few now) coal miners don't get retirements, barely even benefits.
