Mining is the removal of valuable raw materials or other geological materials from the earth, from an ore body, vein or (coal) seam. The term also includes the removal of soil. Materials healthier by mining include base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale, rock salt and potash. Any fabric that cannot be grown through agricultural processes, or created unnaturally in a laboratory or factory, is usually mined. Mining in a wider sense include taking away of any non-renewable resource.Mining of stone and metal has been done since pre-historic times. Modern mining processes involve prospect for ore bodies, analysis of the profit possible of a proposed mine, removal of the desired resources and finally retrieval of the land to get ready it for other uses once the mine is closed.The modern civilization is indebted to the mining industry for extracting the valuable resources from the depths of the earth's surface and it can be mentioned that all the important gadgets used by the modern civilization is supplied by elements extracted through mining.Its contribution to mankind is enormous. The natural mineral substances like solid, liquid and gas were extracted from the earth and used by mankind for various purposes.When we go back to history, it is seen that this process of extraction is closely associated with all ages like Stone Age, Iron Age, steel age, etc. Many important achievements in human history were achieved with the minerals extracted thereby providing a major incentive. By the extraction of these minerals, countries started to accumulate wealth and they were considered as the greatest civilization of the world and those countries that did not extract these minerals were considered to be a country suffering from a lower standard of living.

A miner is a person whose work or commerce is to extract ore or minerals from the earth. Mining is one of the most hazardous trades in the world. In some countries miners lack social guarantees and in case of injury may be left to cope without help. On 21 June , 1935 the Convention No. 45 was adopted by the International Labor Organization, where the Article II establishes exclusion of women work in subversive mines: "No female, whatever be her age, shall be working on underground employment in any mine." The United Mine Workers of America is a North American labor union best known for representing coal miners and coal technicians. Today, the Union also represents health care workers, truck drivers, manufacturing workers and public employees in the United States and Canada. Although its main focus has always been on workers and their rights, the UMW of today also advocates for better roads, schools, and universal health care.Looking at what the nature has to offer, it conveys a lot of information when it comes to things that it holds in it, within it and on it. With need for minerals and its wide spread application getting widened each day, the stint of its very existence is getting blink and its depreciation in its source which is its over usage is on the high. At greatmining.com, we offer you in depth info on the needs, occurrence, and its availability status of each mineral. With the list of minerals ranging from the likes of common salt to the wide spread usage of coal, the elite list of minerals are extremely vast.The dedicated team of prolific mineral enthusiasts provides you with the pristine standard info, about all that you want to know about the varying mineral types. With the vast list of mineral that is available, the need to understand its proper usage and saving it from burning out completely needs a lot of understanding about the minerals that are available.

Heavy machinery is wanted in mining for exploration and development, to remove and stockpile overburden, to break and remove rocks of various rigidity and hardiness, to process the ore and for reclamation efforts after the mine is closed. Bulldozers, drills, explosives and trucks are all necessary for dig the land. In the case of placer removal, unconsolidated gravel, or alluvium, is fed into equipment consisting of a hopper and a shaking screen or trammel which frees the desired raw materials from the waste gravel. The raw materials are then intense using sluices or jigs. Large drills are used to sink shafts, dig stops and obtain samples for analysis. Trams are used to transport miners, raw materials and waste. Lifts carry miners into and out of mines, as well as touching rock and ore out, and equipment in and out of dissident mines.Advancements in mining machinery have meant deeper and deeper open pits have been viable over the last century. Small open pits dug by hand are known historically. The optimum size of mining, rock, and ore hauling equipment is largely determined by the required rates of mining, the length of mine life, and the distances waste rock and ore must be hauled. These trends are apparent in uranium mines as much as any other industrial-scale mines and, with the exception of additional dust control to reduce radiation exposure where required, general mining industry planning and machinery are applied at open pit uranium mines.Old tailings can sometimes be recovered by hydraulic mining or sluicing, where high-pressure water jets are used to both break up the tailings into slurry that can then be pumped for further processing

Coal mining causes a number of damaging effects. When coal surfaces are bare, pyrite also known as fool's gold, comes in contact with irrigate and air and forms sulfuric acid. As water drains from the mine, the acid moves into the waterways, and as long as rain falls on the mine tailings the sulfuric acid manufacture continues, whether the mine is still in service or not. This process is known as acid rock drainage or acid mine drainage. If the coal is strip mined, the entire exposed seam leaches sulfuric acid, leaving the subsoil infertile on the surface and begins to pollute streams by acidifying and killing fish, plants, and water animals which are responsive to drastic pH shifts. Coal mining produces methane, a potent greenhouse gas. Methane is the naturally happening product of the decay of organic matter as coal deposits are formed with rising depths of burial, rising temperature, and rising force over geological time.Coal mining produces methane, a potent greenhouse gas. Methane is the naturally happening product of the decay of organic matter as coal deposits are formed with rising depths of burial, rising temperature, and rising force over geological time.A portion of the methane produced is absorbed by the coal and later released from the coal seam and surrounding bothered strata during the mining process. Methane accounts for 10.5% of greenhouse gas release created through human activity. According to the Intergovernmental Panel on type of weather Change, methane has a global warm potential 21 times greater than that of carbon dioxide on a 100 year time line. While burning coal in power plants is most damaging to air quality, due to the emission of unsafe gases, the process of mining can release pockets of dangerous gases.
