Mining Wikipedia

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Ecological Effects of Subsurface Mining dummies

Surface mining techniques don’t work for extracting all valuable geologic resources. Diamonds and most metal ores, including gold, require extensive subsurface mines to access the rocks with these resources in them. Subsurface mines are probably what you envision when you think of mining: systems of tunnels and vertical shafts with elevators to take miners underground []

Coal mining Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a 'pit', and

Subsurface Geology | WA DNR

Subsurface geology is the study of the physical properties and location of rock and soil found below the ground surface. One of the most valuable reasons for learning about the subsurface is understanding the materials below man-made structures. These studies are commonly called geotechnical reports and are critical for building structures safely in areas with geologic

Quarry Mining, Open-Pit Mining, Strip Mining, Mining

Quarrying is a type of mining and is also called as open pit mining or strip mining. When minerals are found profound beneath the surface, a deep mine has to be dug to dig out them. Quarries are normally dug deeper and bigger; awaiting the mineral resource is worn out. When they are no longer used, quarries are frequently utilized as landfill
