Environmental impact of mining - Wikipedia
27-7-2009 · Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...
Environmental Risks of Mining
Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves large-scale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining …
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.

Open cut mining is the main extraction method in the Hunter Valley. This involves scraping off overburden and digging out a pit to recover the coal. This can result in a whole different set of environmental impacts compared to underground mining. Open cut mining can have major impacts on streams, alluvial aquifers and alluvial soils.
Open-pit mining - Wikipedia
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 ...

Societal Impacts of Large Scale Mining Latin American countries with large scale mining projects have a vast number of social conflicts between mining companies and their governments. According to the Observatory of Mining Conflicts in Latin America (OCMAL) there are currently 120 active conflicts involving more than 150 affected communities throughout the region .
Opencast Mining - an overview | ScienceDirect Topics
The open pit exposes the orebody from the surface by separate removal of ore and associated waste rocks. It is the most economic option for a deposit up to that depth where the economic ratio of ore and waste can be sustained. There are many advantages to the open pit mining method, namely: 1.
