Facts about Mining

Mining

During this period, many Americans (both Caucasian and African American) traveled west by railroad for work opportunities in mining.

Mining

Several steps need to be taken before a mining project can begin.

Mining

Materials recovered by mining include coal, diamonds, limestone, bauxite, phosphate, rock salt, precious metals, iron, nickel, lead, tin, uranium, and molybdenum.

Mining

Mining in the United States became prevalent in the nineteenth century.

Mining

The first mining academy in the world was established in the same town in 1762.

Mining

Mining has also been associated with problems related to miners' health and safety, environmental pollution and degradation, and threats to public health.

Mining

Miners' safety and health have long been issues of concern associated with the mining business, especially subsurface mining.

Mining

One of the most dramatic changes in the mining industry has been the role of sophisticated, three-dimensional mine planning computer software packages.

Mining

Bulldozers, drills, explosives, and trucks are important for digging into the land, especially in surface mining.

Mining

To ensure completion of land reclamation, the Office of Surface Mining requires that mining companies post a bond to be held in escrow until the productivity of reclaimed land has been demonstrated convincingly.

Mining

Mining is the extraction of valuable minerals and other geological materials from the earth, usually from an ore body, vein, or (coal) seam.

Mining

Recent regulations, proper planning, and technological improvements have made mining substantially safer today than it was in earlier decades.

Mining

Mining, like other heavy industries, requires heavy machinery to break and remove rocks that range in their degree of hardness and toughness.
