Overburden

Index Overburden

In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body. [1]

Arboriculture

Arboriculture is the cultivation, management, and study of individual trees, shrubs, vines, and other perennial woody plants.

Archaeology

Archaeology, or archeology, is the study of humanactivity through the recovery and analysis of material culture.

Coal

Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams.

Cosmic ray

Cosmic rays are high-energy radiation, mainly originating outside the Solar System and even from distant galaxies.

Excavation (archaeology)

In archaeology, excavation is the exposure, processing and recording of archaeological remains.

Gangue

In mining, gangue is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit.

Geology

Geology (from the Ancient Greek γῆ, gē, i.e. "earth" and -λoγία, -logia, i.e. "study of, discourse") is an earth science concerned with the solid Earth, the rocks of which it is composed, and the processes by which they change over time.

Impact structure

The term impact structure is closely related to the terms impact crater and meteorite impact crater, and is used in cases in which erosion or burial has destroyed or masked the original topographic feature with which one normally associates the term crater.

Mining

Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, lode, vein, seam, reef or placer deposit.

Ore

An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit.

Particle physics

Particle physics (also high energy physics) is the branch of physics that studies the nature of the particles that constitute matter and radiation.

Root

In vascular plants, the root is the organ of a plant that typically lies below the surface of the soil.

Soil horizon

A soil horizon is a layer parallel to the soil surface, whose physical characteristics differ from the layers above and beneath.

Spoil tip

A spoil tip (also called a spoil bank, boney pile, gob pile, bing, batch, boney dump or pit heap) is a pile built of accumulated spoil – the overburden or other waste rock removed during coal and ore mining.

Surface mining

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.

Tailings

Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, terra-cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore.
