Here is a picture of a coal miner from 1814, when the Industrial Revolution was gathering pace. In the background, there is a steam-powered locomotive, used to transport the coal in waggons along rails, and steam-powered mine machinery, designed to help the miners bring the coal to the surface and to pump out water from the mine.

What is coal gasification? | HowStuffWorks

Coal gasification is said to have greater efficiency than conventional coal-burning because it can effectively use the gases twice: the coal gases are first cleansed of impurities and fired in a turbine to generate electricity. Then, the exhaust heat from the gas turbine can be captured and used to generate steam for a steam turbine-generator.

Overview Of Coal

Electricity : The primary purpose for which coal mining is done is to produce electricity. Once coal is mined, it is taken to coal power stations in truck or train. These power stations need huge reserves of coal to produce electricity on a constant basis. The coal powered station uses coal to produce steam.
