  Basics of an open pit mine

  Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal. In a hard rock mine, the bottom of the pit would be the ...

  Environmental Consequences of Open Pit Mining

  An open pit mine is a type of excavation where surface and subsurface materials (soil and rock) are removed, typically through use of explosives and mechanical mining and hauling equipment, to gain access to commercially valuable ores or other buried natural resources, including coal and gemstones, that are relatively close to the surface. The mined material may be defused throughout the rock ...

  Addressing the issues on openpit mining | BusinessWorld

  To begin with, it is a fact that openpit mining, or mining per se, is not the only human activity that significantly disturbs the environment and cause pollution. Certainly, the development of areas for residential and commercial uses, the clearing of forests to pave way for agriculture, or even commercial fishing, done improperly, will have longlasting ill effects to nature and the people.

  Quarrying granite is difficult and dangerous, even today. Though some of the technology has changed, quarry workers continue to apply their skill and strength to cutting 30 x 30 x 12foot blocks from the rock face one at a time. These blocks in turn are split into smaller 20ton slabs before being hoisted out of the pit.
