Mining is widely regarded as having adverse effects on environment of both magnitude and diversity. Some of these effects include erosion, formation of sinkhole, biodiversity loss and contamination of groundwater by chemical from the mining process in general and open-pit mining in particular. As such, a repeatable process to evaluate these effects primarily aims to diminish them. This paper ...

Once exposed, the ore in the pit is broken up by blasting. A single blast can break approx. 3,000 tonnes of ore. Once the ore is broken, excavators load the ore into haul trucks and transport it to a primary ore crusher where the diamond extracting process begins. The Kimberley Big Hole is an example of open-pit mining. In underground mining ...

Surface Mining. Surface mining includes numerous techniques and is the most common method for non-fuel minerals, producing 97% of the amount mined. Miners choose surface extraction for minerals located close to the surface. There are three main ways to mine on the surface. These methods include quarrying, open-pit mining, and strip mining.
