Basics of an open pit mine

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.

Cost of Stoping for Underground Mining

 · In figure 119, direct stoping costs are plotted against approximate vein or stoping widths, in feet, for a number of mines employing, respectively, open stoping, shrinkage stoping, and cut-and-fill stoping, and thus indicate the effect of width upon direct stoping cost per ton of ore.

Typical Open Cut Grades. Gold is generally extracted in open-pit mines at 1 to 2 ppm (parts per million) but in certain cases, 0.75 ppm gold is economical. This was achieved by bulk heap leaching at the Peak Hill mine in western New South Wales, near Dubbo, Australia. Nickel, generally as laterite, is extracted via open-pit down to 0.2%.
