Pros and Cons of Strip Mining | APECSEC.org

25/02/2015· The Cons of Strip Mining. 1. Bad For The Environment Strip mining can have unwanted effects on the natural ecosystem of the area where the mining is taking place. Plant and animal life is often killed off, taking years to regenerate. In addition to the death of plants and animals, the land also experiences increased susceptibility to erosion and flooding. 2. Contamination Of Water Material is,Ecological Effects of Subsurface Mining - dummies,Surface mining techniques don’t work for extracting all valuable geologic resources. Diamonds and most metal ores, including gold, require extensive subsurface mines to access the rocks with these resources in them. Subsurface mines are probably what you envision when you think of mining: systems of tunnels and vertical shafts with elevators to take miners underground […]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.

Depending on the type of resource being sought, a large amount of ore is removed andStrip Mining - an overview | ScienceDirect Topics,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. In contour or area stripping, the overburden is hauled with different,Environmental Problems of Surface and Underground,Environmental Problems/Impacts Due to Mining.

Subsurface Mining - DoDEA

Subsurface Mining. When mineral ores are too deep to get at with the surface mining techniques, subsurface mining methods are used instead. An advantage of subsurface mining is that it disturbs much less land than surface mining. In fact, it disturbs less than one-tenth the amount of land as surface mining.
