History of coal mining in southern Appalachia, and how it radically transformed the region. Early Appalachian explorers mentioned the fine veins of coal that spread throughout the region. Thomas Jefferson even referred to the abundance of coal in his Notes on Virginia.
But in the 18th and America mining company 19th centuries, there was little use for coal, other than in blacksmith fires. But when the Civil War ended, the United States entered a tremendous industrialization period, and coal was desperately needed to feed the factories and railroads that were spreading across the country like wildfire.
Capitalists from the urban centers of the Northeast, South and Midwest descended in droves into rural areas such as Southern Appalachia to tap into its human and natural resources. The first coal mines in Southern Appalachia were run by small local operators with little financing.
After the Civil War, however, independent coal barons from outside the region set up shop throughout the hills, with better equipment and deeper pockets.
At the turn of the century, many independent operations consolidated into larger ones. This set the stage for the growth of large mining corporations such as U. Steel in later years.
As World War I escalated around the globe, the demand for coal from Southern Appalachia grew to unprecedented heights. At the height of the coal boom, there were nearly 12, mines operating in the region, employing overmen.
Mines in the early days were more primitive and dangerous than the more mechanized mines of today. Miners would dig and blast their way into a hillside, shoring up the walls and ceiling of the tunnel with heavy wooden timbers that they cut from the surrounding forest. They used hand drills to prepare holes to set explosive charges to dislodge the coal.
Mules, and later mining cars, were employed to pull the coal from the depths of the mine shaft. As valuable as mules were, however, they were occasionally sacrificed for the safety of the miners. As mining operations would shut down for the evening, methane gas would sometimes build up in the mine shaft overnight.
To ensure that there was no gas inside, a mule would be sent into the mine first thing in the morning with an open flame carbide or oil strapped on its body.
When the men would hear an explosion or see a smoking mule running out of the shaft, they knew the coast was clear. To handle the influx of workers, mining companies built company homes for them and their families.North America Mining Expo, will forward to your email an e-Expo pass.
