SACMA 2005 Surface Strip Coal Mining Handbook WATERBERG COALFIELD. This coalfield is characterised by coal bearing zones in the shallower part of the field and discrete seams in the deeper portions. The zones, up to 30m thick, consist of narrow coal seams closely interspersed with waste bands. Up to twelve such seams may be identified. The raw ash content of the whole zone can be up

Chapter 1: Introduction - The Strip Mining Handbook

Strip Mining and the Environment From its earliest beginnings, strip mining has been synonymous with environmental controversy. Grossly underregulated coal mining in the 1960's and 70's spawned one of the greatest abuses of the environ­ ment in the history of the United States. The statistics of strip mine abuse numb the mind and overwhelm the ...

Coal Mining and Production - World Bank Group

Strip mining is one of the most economical surface processes. Here removal of overburden and coal extraction proceed in parallel strips along the face of the coal deposit, with the spoil being deposited behind the operation in the previously mined areas. In open pit mining, thick seams (tens of meters) are mined by traditional quarrying techniques. Underground mining is used for deep seams ...

Highwall mining is a coal mining method for recovery of outcropped coal by mechanical excavation without removal of overburden. A continuous miner with single or multiple augers/cutting heads is operated underground and controlled remotely by crew located outside. Augering can be regarded as a supplementary method for open cast mining in cases when coal seams in the highwall would

Surface mining - Wikipedia

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels. Surface mining began in the mid-16th century [dubious ...

Strip Mining: A Destructive Way of Coal Extraction ...

12/03/2017  Surface or strip mining damages and pollutes ecosystems to a great degree. This is because by definition the process of strip mining involves striping away trees, plants and topsoil so that the coal can be accessed underneath. This means that surface mining destroys mountain tops, landscapes, forests and wildlife habitats. On top of that, it leads to soil erosion and destruction of ...

Basic Information about Surface Coal Mining in

Surface coal mining involves: removing parts or all of mountaintops to expose buried seams of coal, and; disposing in adjacent valleys the excess: "overburden" (rock above the coal seam), and "interburden" (rock between coal seams). Overburden and interburden are disposed of in adjacent valleys because the broken rock will not all fit back into the mining pit, and disposal alternatives are ...

The Actual Difference Between Surface and Underground

Open-pit Mining: Removing ore to leave a crater. Quarrying: An open-pit mine for construction materials. Strip Mining: Ore is removed in parallel strips. Mountaintop Removal: Top of a mountain is blasted to remove deep ore. Dredging: Ore is removed from a river bottom. The main methods of underground mining are: Room and Pillar Mining: Removing ore, while leaving behind some for roof support.

What is Surface Mining? - Scottish Coal

Surface mining is just one of many different types of mining that is carried out in the UK. It is when the rock and soil that is covering minerals is removed. The more popular and effective way of mining is underground mining where the minerals wanted are gathered using tunnels, leaving the rock behind. Underground mining is more effective for minerals that are located deep into the earth’s ...

Colliery: How Coal Mining Works? - Science ABC

11/12/2018  In strip mining, the first step is to strip off the vegetation and soil in the vicinity of the surface to be mined for coal. The large intermediate layer of sediment and rock, i.e., the ‘overburden’ is then blasted and removed using large trucks. Once exposed, the underlying coal seam is excavated in strips and transported out using a system of conveyor belts or trucks. The strip mining ...
