To date in the literature, there have not been sufficient LCA analyses of mine processes. It is worth emphasising that this paper is the first to present a computational LCA model for calculating the environmental life cycle assessment for the identified coal mining processes that shows the results of LCA for coal mining operations in Poland.
Conventional coal mining. Conventional underground coal mining relies upon the use of continuous miners in order to extract coal reserves from underground coal seams. In combination with the continuous miners, shuttle cars are used to transport the extracted coal from the face to a transfer point (feeder breaker).
Visualizing the Life Cycle of a Mineral Discovery. Mining legend Pierre Lassonde knows a little bit about mineral exploration, discovery, and development. Drawing from decades of his experience, he created the chart above that has become a staple in the mining industry—the Lassonde Curve.

outside the mining area for placement and storage. In the Midwest, where the surface topography and coal seams are generally flat, it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined ().In some situations in the eastern United States, a coal seam occurring near the top of mountains is ...
The price of coal varies by coal rank and grade, mining method, and geographic region.. Coal is classified into four main ranks—lignite, subbituminous, bituminous, and anthracite—depending on the amounts and types of carbon it contains and the amount of heat energy it can produce.
Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining.
