Mining Engineering is a field that involves many of the other engineering disciplines as applied to extracting and processing minerals from a naturally occurring environment. Engineering is the application of scientific and technical knowledge to solve human problems. ... Minerals are natural compounds formed through geological processes. ...


The need for mineral extraction and production is an essential activity of any technically proficient society. As minerals are produced from within a naturally occurring environment, disturbance of the environment as a result of mineral production is a given. Modern mining engineers must therefore be concerned not only with the production and processing of mineral commodities, but also with the mitigation of damage or changes to an environment as a result of that production and processing. Chuquicamata, the largest open pit copper mine in the world, Chile. ... Look up engineer in Wiktionary, the free dictionary. ... The word commodity has a different meaning in business than in Marxian political economy. ...


The two primary types of mine are underground mines and open-pit mines. Minerals that exist mostly underground (eg. coal, gold etc.) are generally recovered using the underground mining process. Minerals like iron ore, limestone, manganese ore, etc. are mostly recovered from the surface downwards in opencast mining. Chuquicamata, the largest open pit copper mine in the world, Chile. ... Coal Coal is a fossil fuel extracted from the ground by underground mining or open-pit mining (surface mining). ... General Name, Symbol, Number gold, Au, 79 Chemical series transition metals Group, Period, Block 11, 6, d Appearance metallic yellow Atomic mass 196. ... This heap of iron ore pellets will be used in steel production. ... Limey shale overlaid by limestone. ... General Name, Symbol, Number manganese, Mn, 25 Chemical series transition metals Group, Period, Block 7 , 4, d Density, Hardness 7470 kg/m3, 6. ...


Engineering disciplines that are closely related to mining engineering are:

Specialized areas of mining engineering involve extraction of minerals from underwater mines, seawater, in-situ retorting of rock, and underground gasification. The Falkirk Wheel in Scotland. ... Environmental engineering is the application of science and engineering principles to improving the environment (air, water, and/or land resources), to provide healthful water, air and land for human habitation and for other organisms, and to investigate the possibilities for remediation of polluted sites. ... Bostons Big Dig presented geotechnical challenges in an urban environment. ... Hydraulic engineering is a sub-discipline of civil engineering concerned with the flow and conveyance of fluids, principally water. ... This article treats electronics engineering as a subfield of electrical engineering, though this is not typical use in some areas. ... Taipei 101, the worlds tallest building as of 2004. ...

Blasting

Using explosives to break up a rock formation and aid in the collection of ore is called blasting. There are two types of blasting: high velocity and low velocity. High velocity blasting uses explosives that have high rates of reactions and produce high pressures (i.e. high explosives). Low velocity blasting is done with explosives which have a low rate of reaction and thus low pressures (i.e. low explosives). Blasting is done in selected regions where the ore is available. The size of the ore after blasting varies. This article is concerned solely with chemical explosives. ... Iron ore (Banded iron formation) Manganese ore Lead ore Gold ore An ore is a volume of rock containing components or minerals in a mode of occurrence which renders it valuable for mining. ... Rock blasting is the controlled use of explosives to excavate rock. ... This article is concerned solely with chemical explosives. ... Preparing C-4 explosive This article is concerned solely with chemical explosives. ...


Mineral prospecting

Mining operations start only after geophysical survey. A geological survey will develop a projection of the size and purity of an ore deposit. Based on these projections, more detailed studies may be ordered. This is known as detailed prospecting. One of the methods of prospecting is to extract core samples from the area of the potential mine. The cross sections of these cores can be used to develop a three-dimensional projection of the mineral deposit. Electrical resistance map of ancient Aphrodisias EM conductivity survey Magnetic gradiometer map of Prehistoric fire-hearths GPR survey // Overview Geophysical survey most often refers to subsurface imaging techniques used in archaeology. ... ... Prospecting is the act of searching for minerals or ore deposits. ... A core sample is a cylindrical section of a naturally occurring medium consistent enough to hold a layered structure. ...
