Mine Waste Transfer and Disposal Methods - Mine

Overburden. Waste rock or overburden refers to the often large mass of initial soil and rock that is removed to get to the valuable mineral deposits. Typically, for every ton of ore that is mined, 5 tons of overburden is displaced. Overburden is not subjected to any chemical processes but must be removed to access the ore underneath.

Overburden - Wikipedia

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. Overburden is distinct from tailings, the material that remains after economically valuable components have been extracted from the generally finely milled ore. Overburden is removed during surface mining, but is typically not contaminated with toxic components. Overburden may also be used to restore an ex

In surface mining, the overburden will be removed and dumped aside, thus waste produced will be much higher than the coal or ore extracted based on stripping ratio. Almost every coal as well as metal mining produces waste rock. The quantity of waste produced (shale and sandstone) in coal mines is in-terms of millions of cu.m per year.

The volume of overburden and mine waste will exceed the pre-disturbance volume of the mined pits (voids) by approximately 30%. This is because the volume of the overburden when broken and transported is greater than the volume of the overburden plus ore in situ. Excess overburden will be placed in permanent storage areas outside the mine pit area.

The amount of waste rock that needs to be removed depends on the geometry and location of the ore body, mining method and the composition and stability of the bedrock. The ratio of waste rock/ore is called stripping ratio. For example, a stripping ratio of 2:1 means that 2 tonnes of waste rock needs to be removed to mine 1 tonne of ore.
