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.
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 June 21, 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 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.
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.Read more.....
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.
