Unusual Mining Operations

In an underground mine the finest shaped ore body is almost vertical, due to the fact that this makes possible the use of gravity to collect ore for transport to surface. If the ore body is flat, and in particular if it is also thin, this inflicts an extra load on the mine since the ore needs to be mechanically moved at all stages. Breast stopping is a process that is used a lot in the flat dipping South African gold fields but has not been seen that much anywhere else. This comparatively labor intensive method has seen some improvements as far as support methods and drilling technology, but the essential methodology has not varied that much over the years due to the fact that the narrow flat-lying nature of the reefs in South Africa make mechanization extremely complicated.

Mining Operations: Mining, in its broadest sense has to do with the procedure of getting hold of useful minerals from the earth’s crust. The development consists of excavations in underground mines and surface excavations in open-pit, or open cut mines. Additionally, recent technological developments might soon make inexpensively feasible the mining of metallic ores from the seafloor. Mining in general means an operation that has to do with the physical removal of rock and earth. A number of substances, particularly natural gas, petroleum, and some sulfur, are produced by certain methods that are not classified as mining.

A mineral is by and large defined as any substance that occurs naturally of definite chemical composition and consistent physical properties. An ore is a mineral or grouping of minerals from which a valuable or useful substance, such as a metal like gold, can be extracted and sold at a price that will recover the costs of mining and processing and render a profit as well. The naturally occurring substances are normally split into metalliferous ores, like the ores of gold, iron, copper, lead, zinc, tin, and manganese, and the others are non-metalliferous minerals that include coal, quartz, bauxite, trona, borax, asbestos, talc, feldspar, and phosphate rock. Building and ornamental stones that structure a different group are made up of slate, marble, limestone, trap rock, travertine, and granite.

Almost all the minerals can be located in veins, or tabular shaped deposits of non-sedimentary origin, in many cases dipping at high angles, in beds, or seams that are tabular deposits that conform to the stratification of enclosing rocks, and as masses, or large ore bodies of irregular shape standing at any angle. Gold, diamonds, tin, and platinum can in many cases be found in placers or deposits of sand and gravel that has particles of the mineral.
