Surface mining at these scales is more economical for coal companies, safer for miners, and, coal operators say, essential for mining the thin seams of lower-sulfur coal more valuable in today’s market. With dynamite and immense machines, surface mines can produce more than two to three times as much coal per miner as underground mines can.

Thus, surface coal mining is more likely than underground mining to affect the health of nearby residents. Appalachia has a long history of coal mining as a predominant industry. However, increased mechanization in the mining industry has conferred relative cost advantages for other regions and has led to reduced coal production in Appalachia.
