Control Of Open Pits In Small Scale Mining:

openpit mining openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. the word is used to distinguish this type of mining from extractive methods that need tunneling into the earth. buy nowIn open-pit mining waste is transported to a disposal site, and the ore is transported to a downstream processing site. this method commonly involves a sequence of benches from the surface to the deposit. As the open pit goes deeper into the ground, all of the benches above are extended outward.sensitivity of specific ecosystems to mining is examined in box .1. the most obvious impact to biodiversity from mining is the removal of vegetation, which in turn alters the availability of food and shelter for wildlife.
