Open Pit Mining Pros & Cons
Open pit mining is also called strip mining because the extraction process destroys vegetation, reduces habitats and pollutes the environment. Mining proponents argue that the process is more efficient, cost effective and safer than shaft mining. Environmental regulations help mitigate damage.

What are the advantages and disadvantages of open-pit …
Explanation: Shallow mineral or coal deposits can be economically mined by open-pit or strip mines. However, with deeper mineral or coal deposits it becomes very costly to remove a great deal of overburden in these kinds of settings. So, in these cases underground mining is more cost effective.

Mining and Water Pollution — Safe Drinking Water Foundation
Open-pit mining involves the excavation of large quantities of waste rock (material not containing the target mineral) in order to extract the desired mineral ore. The ore is then crushed into finely ground tailings for processing with various chemicals and separating processes to extract the final product.

Environmental Risks of Mining
Open pit mining. 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.
