non-renewable energy | National Geographic Society

Surface mining is used when the coal is located very near the surface of the earth. To get to the coal, companies must first clear the area. They take away the trees and soil. The coal can then be cut out of the ground more easily. Entire habitats are destroyed during this process.

Surface mining, which is only effective for shallow deposits, often employs highly invasive techniques, including area strip mining and mountaintop removal.

Appendix E: Coal Mining and Processing Methods | Coal ...

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the ...

Coal mining | World Coal Association

The coal industry takes the issue of safety very seriously; modern coal mines have rigorous safety procedures, health and safety standards and worker education and training. Methane released from the coal seam and surrounding rock strata during mining can present a high risk of explosion at concentrations in air of 5-15%.

A Citizen''s Guide to Mining and Reclamation in Ohio

Petroleum engineers generally work in offices or at drilling and well sites. Travel is frequently required to visit these sites or to meet with other engineers, oilfield workers, and customers.

Methane Emission in Coal Mines--the Effects of Oil and Gas ...

The method of moving averages was found useful in assessing the nature of methane emission in coal mines. Emission rates were influenced markedly by the presence of abandoned oil and gas wells in the vicinity of the mine. Such wells appeared to increase the flow rate of methane into the mine by a factor

How Are Fossil Fuels Extracted From the Ground? | Sciencing

 · Coal can be extracted close to the upper portion of the earth''s crust, called surface mining, or from deep within the earth through underground mining. Recovering coal through surface mining is relatively easy; shovels and bulldozers are effective at extracting coal near the surface. Once depleted, workers replant a surface mine and move on.

Crude Oil Extraction and Drilling Methods | CAPP

Surface Mining. Oil recovery in the oil sands uses two main methods: mining or in situ, depending on how deep the oil sands deposits are. Surface mining is used when oil sands deposits lie within 70 meters (200 feet) of the earth''s surface. Twenty per cent of oil sands reserves are close enough to the surface to be mined.


11.G.1. Description. Mining water use includes water used for the extraction and on-site processing of naturally occurring minerals including coal, ores, petroleum, and natural gas.
