Surface mining – strip, open pit, mountaintop removal, dredging

Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surface ...

The legacy of surface mining: Remediation, restoration ...

Dec 01, 2016  1. Introduction. In surface mining, soil and rock overlying or hosting a shallow ore deposit is physically removed to access the resource. Surface mining comprises different practices − strip mining, open-pit mining and mountaintop-removal mining − and accounts for more than 80% of ore mined each year (Ramani, 2012).Surface mining disturbs the landscape and impacts habitat integrity ...

Basic Information about Surface Coal Mining in Appalachia ...

Coal seams are removed with excess soil and rock placed in an adjacent valley. Large scale earth moving equipment is used to excavate and remove coal from lower layers. The equipment used depends on the method and scale of the surface mining method being employed. Regrading begins as coal excavation continues.

Surface Mining Techniques used in the Oil Sands Oil ...

SURFACE MINING ≠ STRIP MINING: Although sometimes mistakenly referred to as strip mining, oil sands is actually mined from an open-pit below several meters of overburden.Strip mining is the mining of a relatively flat deposit very close to the surface, commonly used in coal or phosphate industries.

Oil sands surface mining - Energy Education

Surface mining is a technique used to obtain bitumen from oil sands where the oil sands deposits are located 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 ...

Surface Mining and Reclamation WA - DNR

Surface mining reclamation restores vegetation, soil stability, and proper water conditions after mining. Each site will be completed differently depending on the future use and reclamation law. However, the work completed prevents future environmental degradation and prepares the site for its future use.

The Actual Difference Between Surface and Underground Mining

Surface mining is suitable for large, low-grade ore deposits which occur below a thin layer of rock, or alluvial deposits found in sand and riverbeds. Underground mining is used for small, high-grade deposits covered with a thick overburden (soil and rock above the ore), or for deep and sloping deposits.

Mar 15, 2011  Surface mining is one of the most complete forms of human-caused habitat alteration and degradation (Fischer and Fischer, 2006). Mining eliminates vegetation, removes soil and overburden by excavation, changes topography and geological structures permanently, and disrupts surface and subsurface hydrologic regime.

Strip mining Britannica

Strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral.. The common strip-mining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type. The cycle of operations for both techniques consists of vegetation clearing, soil removal, drilling and blasting of ...

Mining Erosion Protection Control Watershed Geo

Mining can create some environmental challenges, including mining erosion, sinkholes, soil contamination, and surface water contamination by chemicals from mining processes. Furthermore, there can be several high flow drainage channels that need to be maintained constantly to prevent excessive erosion.

Impact of surface coal mining on soil hydraulic properties

Surface coal mining disturbs large areas of land, increas-ing the potential for surface runoff and soil erosion (Mum-mey et al., 2002). Surface mining in the western United States operates under noticeably different environmental conditions from those in other regions of the country. Most of the western U.S. coal mining areas are located in ...

Surface Rights vs. Mineral Rights: What’s the Difference ...

Both mineral and surface rights can also have co-ownership. If the surface rights owner wants to retain a partial stake in the mineral rights below their property, they have the option to only sell off a percentage of their mineral rights. Or, they can sell the mineral rights to multiple buyers, giving each a specific section of land.

Surface mining techniques are categorized as either strip, open pit, or mountaintop removal. Strip mining is a method used on flat terrain and involves removing soil or rock above a layer of coal, exposing the coal seam for mining. One type of strip mining is contour mining, where extraction activities occur on a hillside.
