Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
MINING METHODS AND COAL PROCESSING TECHNOLOGY INTRODUCTION Mineral exploitation in which all extractions are carried out beneath the earth''s surface is termed as underground mining. Underground mining methods are employed when the depth of the deposit, the stripping ratio of overburden to ore (coal or stone), or both become
Coarse Coal Flotation Circuit. It is highly desirable to extend the range of coal flotation to include the coarser Sizes. Not only will this simplify general washery practice but will result in a superior product having desirable marketing characteristics for metallurgical and steam power plant uses.
Coal is not an ore. Ore requires extraction to obtain the element while coal is already in its usable form. In RuneScape, coal rocks have a higher chance of awarding gems than other mined resources. One can observe this in the real world as well. In the real world, coal beds can supply the needed carbon and pressure that gems require to form.
The total amount of hard coal and ore mining and processing waste laying in dumps at the end of 2000 was Mt that was % of total amount of all wastes disposed throughout the country. Of that, hard coal mining waste comprised % and metal ore (copper) mining and processing, %.
Metallurgical coal is more scarce and valuable than thermal coal, so in practice metallurgical coal is rarely used to generate electricity. Metallurgical coal is also commonly referred to as coking coal. Coking coal has physical properties that when heated cause it to soften, liquefy and then resolidify into a harder substance known as coke.

Processing the Coal. 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. Source: Energy Information Administration
