coal mining, extraction of coal deposits from the surface of Earth and from underground. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the large-scale exploitation of …
This is performed by a mechanical cutter that shears coal off from a panel on the seam. The panel being worked on may be up to 800 feet in width and 7,000 feet in length. Mined coal is deposited onto a conveyor that moves the coal to a collection area. Hydraulically powered shields over the machine provide ceiling support.
Ventilation control of dust in coal mines is important in the different types of underground coal mining such as (1) room and pillar mining, (2) longwall mining and (3) shaft mining. Type (1) is done in an ore deposit where some of the ore is left behind to form columns in the mine that prevents it from collapsing and it is used for coal mining ...
