For mining purposes, big machines are often used in order to make the mining process more effective and to reduce the physical work for miners. However, these machines emit large amounts of harmful gases, also including greenhouse gases like methane or CO2. Thus, mining can also cause air pollution and the implied consequences.

Surface mining is a technique used to obtain bitumen from oil sands where the oil sands deposits are loed fairly close to the surface. If the reserves are shallow enough, earth moving equipment can dig out oil sand for processing. These deposits must be within 75 meters of the surface to be mined in this fashion. Resources recoverable by this type of extraction are estimated to be 65 ...
· Sand mining has occurred in Wisconsin for hundreds of years; however, recently there has been a dramatic increase in the number of mining proposals. This increase is attributed to a surge in hydrofracking, a technique used by the petroleum industry to extract natural gas and/or crude oil from rock formations, which requires a certain quality of sand in the process. Wisconsin possesses high ...

Oil sands mining involves excavating oil sands using trucks and shovels and transporting it to extraction plants to separate the bitumen from the sand. To separate bitumen from Alberta's oil sands, mining operations transport materials to large processing and upgrading facilities that require large volumes of readily available water for the bitumen separation process.
Frac Sand Mining. Hydraulic fracturing uses high pressure water to break open underground geologic formations – most commonly shale. – containing oil and gas. Once the shale is fractured, if the fractures are not propped open, they will close again. So frackers use frack sand to prop open the fractures to allow the oil and gas to be extracted.
