Andrew P. Schissler, in Encyclopedia of Energy, 2004 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.
Strip mining is considered very harmful to the environment. Proponents of strip mining cite its better efficiency, cost, and safety as compared with traditional underground mining techniques. The recovery rate of materials is higher with strip mining, with approximately 80% to 90% of the material being recovered, as opposed to only approximately 50% with tunnel mining.

Impacts of strip mining: Strip mining destroys landscapes, forests and wildlife habitats at the site of the mine when trees, plants, and topsoil are cleared from the mining area. This in turn leads to soil erosion and destruction of agricultural land. When rain washes the loosened top soil into streams, sediments pollute waterways.
Jan 13, 2018· Rain can also push the filth of the mine on the topsoil making it inhabitable for plants and animals. The water in the region becomes impure due to the pollution.

Renewable energy reduces a host of other environmental threats, such as mercury pollution that poisons fish and wildlife in our waters, acid rain that harms our lakes and forests, as well as smog and haze, damaging coal strip-mining, and toxic wastewater discharges from power plants.
The negative effects of coal mining cannot be disputed: Destruction of Landscapes and Habitats: Strip mining also known as surface mining, involves the stripping away of earth and rocks to reach the coal underneath. If a mountain happens to be standing in the way of a coal seam within, it will be blasted or levelled - effectively leaving a ...
Wild animals and cows are going into the strip-mine and drinking from the toxic pool of water that is accumulating there, and the people who consume them likely have no idea of the threat they are being exposed to. The company likes to talk about how 'natural' its solvents are.

Those who advocate for strip mining believe that the recovery rate of materials is higher using the method. It is estimated that about 80 to 90% of the material can be recovered compared to the 50% recovered using tunnel mining.
Sep 28, 2018· In some countries, mining is responsible for significant amounts of water use, as well as water waste. Environmentally, potential negative effects of mining can include air, land/soil and water pollution of different kinds. Mining produces potentially hazardous/toxic tailing waste, and can leach toxic chemicals, heavy metals and air pollutants.
