Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals.This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
Open cast mining involves the removal of overburden including the valuable topsoil and plus the natural vegetative cover to meet the ore deposits.These activities are associated with harmful effects to the local environment.Mining activities are carried out in various stages, each of them involving specific environmental impacts.

Surface mining techniques are used when a vein of coal or other substance lies so close to the surface that it can be mined with bulldozers, power shovels, and trucks instead of using deep shaft mines, explosive devices, or coal gasification techniques.Surface mining is especially useful when the rock contains so little of the ore being mined that conventional techniques, such.
Surface mining, method of extracting minerals near the surface of the earth.The three most common types of surface mining are open-pit mining, strip mining, and quarrying.See also mining.
The studies look at the impact of mining on surface and ground water, soils, local land use, native vegetation and wildlife populations.Computer simulations can be undertaken to model impacts on the local environment.The findings are then reviewed as part of the process leading to the award of a mining permit by the relevant government.
Mining is the extraction of minerals and other geological materials of economic value from deposits on the earth.Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil.
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.
On the right side, the same watershed is shown after the mountain rock layers have been removed, crushed, and deposited in the stream valley.Flat surfaces of remaining rock layers are less permeable, producing higher surface runoff into a flood control.
