Also known as “soft coal”, bituminous coal is the type found in Cape Breton and is our most abundant fuel. It is greatly used in industry as a source of heat energy. Anthracite – Stage Four Anthracite, the fourth stage in coal formation, is also known as “hard coal” because it is hard and has a high lustre.

Coal can be transported from mines and processing plants to consumers in several different ways: Conveyors, trams, and trucks move coal around mines, short distances from mines to consumers close to the mines, or …

Called ‘Open-cast’ if soft-rock mining (eg coal or limestone) and ‘Open-pit’ if hard- rock mining (eg copper and diamonds). The mining process is fundamentally different between these soft- and hard-rock operations.

Mining: Mining, process of extracting useful minerals from the surface of the Earth, including the seas. A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure.

The Mining Process. The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed.

Coal mining is a vital industry in the world's economy. According to the World Coal Association, coal provides 42 percent of global electricity generation. Coal mining occurs both on the surface and underground, lending itself to a wide variety of jobs.

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 …

After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal.

Mountaintop removal mining involves taking off the top of the mountain to reach the ore underneath and is usually associated with coal mining. Most surface mines only extend to about 650 feet, after which the underground mining method is used.

Surface mining is only economic when the coal seam is near the surface. This method recovers a higher proportion of the coal deposit than underground mining as all coal seams are exploited - 90% or more of the coal can be recovered.

The overall coal mining process consists of several sequential stages: (1) exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; (2) analysis and selection of a mining plan; (3) securing the markets; (4) developing the mine; (5) extracting the …
