A four foot coal bed is overlain by 75 feet of overburden: calculate overburden volume using an area of 1 yard long by 1 yard wide: 75 ft./3 ft. per yard = 25 yards depth volume = 25 yds. depth x 1 yd. wide x 1 yard long volume = 25 cubic yds. of overburden. calculate volume of coal in 1 yd. by 1 yd area (convert yds. to ft.)

Coal Miners Working Inside the Mine, 1908 (gallery) Coal miners worked long hours inside the mine, often traveling by elevator deep underground to extract coal from the coal seam. In the nineteenth century, miners worked largely by hand alongside animal labor. As new technology emerged, underground mining increasingly depended on heavy machinery.

Mining is one of the most vital components of modern society due to the use of mined minerals in almost every consumer product. Additionally, 50% of the nation's energy comes from coal or nuclear power that uses uranium. To support this need for modern equipment, mines are found in all 50 states, including our home state of Nevada.

The engines powered by steam increased the ease of operating boats, ships, railways, factories, mills, mines and farms. And these steam engines were fueled by coal. The history of coal use in England stretches back far earlier than the development there of the steam engine. It has been mined and used at least since the Romans occupied the island.

The steam engine needed coal for its fuel, and so when the invention was made more efficient and adapted for other uses by such inventors as James Watt (1736-1819) and Matthew Boulton (1728-1809), so the demand for coal grew. Steam engines were used to power cotton looms, steam hammers, threshing machines, and any other kind …
