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 recoverable.This is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining. The particular characteristics of the coal mining industry create unique

The U.S. coal industry serves a vital role in the nation’s economy by producing fuel for more than half of its electricity. Despite the industry’s importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2

Coal Mining: How Is Coal Mined? Science ABC

Jan 07, 2021 Underground Mining. Room and pillar and longwall are two dominant methods that account for the vast majority of underground coal mining.. Room and Pillar Mining. In this mining strategy, seams of the coal are mined partially, leaving large pillars of coal intact in a bid to support the overlying layers of rock.

Basic Information about Surface Coal Mining in Appalachia

Coal seams are removed with excess soil and rock placed in an adjacent valley. Large scale earth moving equipment is used to excavate and remove coal from lower layers. The equipment used depends on the method and scale of the surface mining method being employed. Regrading begins as coal excavation continues.
