Today, the price of oil is relatively high and extraction technology is becoming more efficient and less expensive. The possibility of mining oil shale has again become a possibility. Communities, governments, oil companies, and environmental organizations must weigh the cost of extraction with the benefits of an oil resource.
Geography is an academic discipline and subject of study that explores—and promotes critical thinking about—how the world is organized, the environments and patterns that exist on the ground or that humans create in their minds, the interconnections that exist between the physical and human environment, and the nature of places and regions.
Oil shale is a type of sedimentary rock that is rich in kerogen. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. Hydrocarbons are substances made entirely of hydrogen and carbon. Petroleum and natural gas are probably the most familiar . hydrocarbons.The hydrocarbons in oil shale can be used as an alternative to petroleum or …
The extraction of resources refers to the withdrawing of materials from the environment for human use, including fossil fuels (oil, gas, and coal), rocks and minerals, biomass via deforestation and fishing and hunting, and water.Since the first coal-fired steam engines of the 1700s, we continue to increase the rate at which we extract and transport resources for use across the globe.

Today's infographic from Excelsior Mining Corp. outlines a unique mining method, In-Situ Recovery "ISR", also known as In-Situ Mining. An Intro to In-Situ Mining. ISR is not a recent innovation in the mining sector. In fact, ISR has been used for the past 50 years in uranium mining, and 48% of the world's uranium gets mined this way.
Cost–benefit analysis (CBA) is the standard methodology for judging if a policy makes best use of available resources, by systematically comparing the total range of benefits and costs accruing to the policy (HMT, 2011; Kind, Botzen, & Aerts, 2016; NZT, 2014). Even though flood zoning regulations are not exempt from this requirement, there ...
The other is whether local communities benefit from mining in their area. Prior to enactment of the Mineral Resources and Petroleum Development Act of 2002, which vested custodianship of all mineral resources in the state, local communities sometimes had freehold rights, in terms of which they had ownership of mineral resources in their land ...
In several low- and middle-income countries rich in non-fuel mineral resources, mining makes significant contributions to national economic development as measured by the revised Mining Contribution Index (MCI-Wr).

The South African economy overall continues to benefit greatly from mining, but it is not benefiting as much as it could, and the costs of mining are increasingly borne by communities in rural areas. Mining accounted for 7 per cent of GDP, $20.7b worth of primary exports and employed 459,000 people in 2006.
1. Open Cast Mining - Method of extracting minerals which are near the earth's surface. - The types of open cast mining include: a) Stripping - Stripping off of the unwanted material lying on top of the mineral deposit and then digging to remove the mineral bearing rock if it's soft or if it's hard explosives may be used to loosen it and then huge power shovels are employed to dig up …
Despite mining occupying a smaller geographical area compared to other land use/land cover (LULC) classes, it exhibits strong interconnections with various land uses and …
Groynes. Groynes are wooden barriers constructed at right angles to the beach to retain the material. The beach material, including sand and pebbles, is trapped between groynes and cannot be transported away by longshore drift.Groynes encourage a wide beach that helps absorb energy from waves, reducing the rate of cliff erosion.
However, despite their larger spatial extent, critical mining areas are less dense than other mining areas (2.0 vs. 3.5 for operational mining properties; Supplementary Table 2), due to ...
There are three major types of underground coal mining: longwall mining, room-and-pillar mining, and retreat mining. Underground Mining: Longwall Mining During longwall mining, miners slice off enormous panels of …
In mining it involves identifying the benefits of mining projects. These benefits are assessed against the costs of the mining project. If the costs are too much compared to the benefits, the mining project may be stopped. Costs of a mining project include financial, social and environmental costs. Financial costs are determined by:
