What are 2 methods used to mine coal out of the ground to make electricity?

The two typical types of coal mines are tunnel mines, where the coal vein is dug out by tunneling into it, or "Open Pit" mines, where the coal and surrounding rock are dug out in a large pit and separated. The type of mine used is often determined by the hardness of the surrounding rock, hard rock is often avoided and the coal tunneled out of it. Soft rock or soil is more safely and easily handled with open pit mining. This often produces low grade waste known as "culm" which is poor quality carbon deposits.


How deep down is a bituminous coal mine vertical shaft?

There are 2 kinds of coal mine shafts-- slope or dug horizontally then down, or a vertical shaft dug nearly straight down. Some coal mines use both--a wide tunnel dug as a slope, then down. However, in the 1800s, they often crawled into a slope mine.Depth of either type, and for either bituminous coal or anthracite coal, can be 1,000 to 2,000 feet underground. Most mines also have labyrinths of tunnels throughout, which can go to different depths.
