Openpit mining Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clearcutting or burning of vegetation above the ore deposit may precede removal of the overburden. The
Openpit mining is to be considered one of the most dangerous sectors in the industrial world. It causes significant effects to miners health, as well as damage to the ecological land. Openpit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths.

In 1989, U. S. Environmental Protection Agency completed capping cracked and caved ground areas and the open pit mine on Iron Mountain. OffSite Disposal Removing contaminated solid mining waste and capping or covering the waste off site is supported by the public as the risk of exposure to the contaminants has been removed.
emeralds, gold, uranium, nickel, coal and iron ore. Minig takes place in a spectrum if large, small and artisanal mines. Open pit mining and stripping is done by removing soil and vegetation from the surface to access the ore. Explosives are often used widely spreading chemicals and dust including into
Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts. As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced, tremendous volumes of waste rock are removed from the pits and deposited in .
Aug 26, 2008· Abstract. 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 openpit mining .
Air quality management: a mining perspective F. Schwegler Anglo Technical Division, South Africa Abstract Air quality management issues relating to mining are mainly centred around particulate impacts. These include dust deposition, and health impacts associated with PM10 and and the mineralogy and chemical composition of the particles.
The DNR''s staff has refrained from taking positions on iron mining since Gogebic Taconite in the spring of 2011 unveiled plans for a massive open pit mine in portions of Ashland and Iron counties.
Mar 21, 2018· A very good question indeed! Mining has adverse effects both on miner and environment. Mining is necessary for minerals extraction, but at the same time it has some adverse effect on health The effect of mining includes erosion,, formation ofsink...
Mine development includes the construction of mining infrastructure and the commencement of ore extraction. It is not uncommon for a new mine to be several years under development before ore is actually extracted. Types of Mining In open pit / open cast mining, overburden material (soil and surface rock) is stripped and stockpiled. The ...

to fossil fuels, coal, and metal mining (Matthews et al., 2000:107). The amount of waste produced depends on the type of mineral extracted, as well as the size of the mine. Gold and silver are among the most wasteful metals, with more than 99 percent of ore extracted ending up as waste. By contrast, iron mining is less wasteful, with
Underground copper mining in Butte, Montana since the 1870''s has resulted in over 49 miles of vertical shafts and 5,600 miles of horizontal workways. In 1955, high copper prices drove Anaconda Copper Mining Company to open a new pit mines including the Berkeley Pit.
