The cost of this preparatory work is obviously a charge against the cost of mining the ore, each ton of which must bear its proportionate share. As the strippingore ratio (volume or tons of overburden and capping to tons of ore made available for openpit mining) increases, obviously the cost of stripping per ton of ore increases.

Most underground clay mines are located in Pennsylvania, Ohio, and West Virginia, where the clays are associated with coal deposits. A higher percentage of fire clay is mined underground than other clays, because the higher quality fire clay deposits are found at depths that make openpit mining less profitable.

A pit, sometimes called a borrow, is dug in an area. This pit becomes the openpit mine, sometimes called a quarry. Openpit mines can expand to huge dimensions, until the coal deposit has been mined or the cost of transporting the overburden is greater than the investment in the mine. Openpit mining is usually restricted to flat landscapes.
