Through the middle of the 19 th Century, the coal industry expanded and spread. Ohio produced over a million tons of coal by 1853, and by 1861 coal mining had expanded to 20 states. At the time, coal mining operations remained small businesses. A skilled miner could employ a few laborers to extract coal close to the surface.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.
By 1920, the use of draglines and other modern equipment made strip mining possible and the privately owned Grand Lake area mines produced over 200,000 tons per year. Most of this coal was used by the railroad and large businesses. By 1936, a coal burning electric power generating plant at Newcastle Creek was operating with two 33,000 volt ...
The coal is then loaded on to large trucks or conveyors for transport to either the coal preparation plant or direct to where it will be used. Mine rehabilitation. Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped.

At first, there were no safe, permissible types of explosives nor certified permissible equipment of any kind for use in U.S. coal mines. To be classified as permissible for use in underground coal mines, explosives now had to pass a series of scheduled safety and performance tests. In 1910, the following USBM projects were underway in Pittsburgh:
Underground mining operations around the world pose similar risks to worker safety and health. Though different techniques are used to extract base metals, precious metals, nonmetallic minerals, diamonds and coal, the hazards do not differ that much.
Mining Techniques & Equipment. Over the past 250 hundred years, the coal mining industry has witnessed significant changes to both its mining techniques and the equipment used throughout the mining process. Changes evolved through a need to make a safer underground environment for the thousands of miners employed in Cape Breton's coal industry.
