Coal remains a very important source of energy for the global economy. Surface and underground coal mining are the two major methods of coal extraction, and both have benefits and drawbacks. Surface coal mining can have a variety of environmental impacts including ecosystem losses, landscape alteration, soil destruction, and changes to surface and groundwater quality and quantity. In addition ...

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the ...

In this article, we demonstrate that despite the renewablesled rhetoric, India is in the midst of a transition to (not away from) greater use of coal in its fossil energy system and in the electricity system in particular. We investigate this paradox by combining sociometabolic and politicalecological analysis of the Indian coal complex.

Two dominant methods account for the vast majority of underground coal mining: "room and pillar" and "longwall" mining.. In room and pillar mining, seams of coal are partially mined, leaving large pillars of coal intact to support the overlying layers of rock. When finished, miners practice "retreat" mining, extracting as much coal as possible from the remaining pillars as they ...
