Open-pit mining, also known as open-cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburdenis relatively thin or the

ExtractionRehabilitationTypical Open Cut GradesReflection QuestionsOpen-cast mines are dug on benches, which describe vertical levels of the hole. These benches are usually on four to sixty meter intervals, depending on the size of the machinery that is being used. Many quarries do not use benches, as they are usually shallow.Most walls of the pit are generally dug on an angle less than vertical, to prevent and minimize damage and danger from rock falls. This depends on how weathered the 在courses.lumenlearning上查看更多信息

Deep open cut mining, Fig. 1, is one of the most energy intensive forms of mining.In part, this is due to the use of large haul trucks to lift ore and overburden from the mine. As a haul truck lifts a load, typically 100–300 tonnes, from the bottom of an open cut mine to the surface, energy is expended in lifting the truck itself, typically of mass 100–300 tonnes, from the mine.

Open Pit Mining Pros Cons Sciencing

Open-pit mining is much safer than shaft mining. In underground mining, the threat of a cave-in or release of toxic gas is a constant concern. When shaft mining was the most common method of ore extraction, thousands died in cave-ins, gas events and accidents involving equipment. In 1907 alone, more than 3,200 deaths related to mining occurred.
