Open Pit Mining. Open pit mining is similar to area mining. The technique is common in the western United States (and other parts of the world) where very thick — 50 to 100 foot — coal seams exist. Open pit mines are usually large operations. Production levels may exceed 10 million tons of coal per year.. The thick coal seams found at these large mines ensure that the amount of land ...

There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, which forms the mineralized package of economic interest to the miner.. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot ...

Open pit mining is usually found where coal seams are thick. Open pit mines can reach depths of a hundred metres. Equipment used in surface mines include draglines, shovels, bulldozers, frontend loaders, bucket wheel excavators and trucks. In large mines, draglines remove the overburden while shovels are used to load the coal.

Open pit mining results in two waste streams: waste rock which contains no economic quantity of minerals but which must be removed to gain access to the orebody, and tailings which are the result of a mineral separation process in the concentrator or processing plant. The mining rate includes the mining of both waste and ore.
