pros and cons of open pit mining

Open Pit Mining Pros Cons Sciencing

25-06-2018  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.

Open pit mining pros cons - eHow

Pro: Easier Extraction The biggest advantage of open pit mining is the relatively low cost-extraction ratio. Open-pit mines are chosen when deposits of valuable minerals are found beneath the surface and where there overburden (overlaying rock or earth) is relatively thin.

The Mining Life: Open Pit vs. Underground -

Open pit mines don’t have to safeguard against loss of air and cave-ins, but they do have their own set of strict safety guidelines that save lives. While there isn’t as much of a danger of cave-ins, rock slides and other hazards due to the structural integrity of the material the miners work in are still present.

Mining - Surface mining Britannica

Open-pit mining often (but not always) results in a large hole, or pit, being formed in the process of extracting a mineral. It can also result in a portion of a hilltop being removed. In strip mining a long, narrow strip of mineral is uncovered by a dragline, large shovel, or similar type of Crusher.

A deeper look - Ontario Nature

ground mining is generally used for deeper, concentrated deposits5. Open pit mining is used to extract ore deposits that are located close to the surface, since, on average, the cost per tonne of ore mined is lower than that for underground mining. Open pit mines result in a larger area of surface disruption and tend to produce much larger amounts of waste rock6.
