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 Is Open Pit Mining?
Strip mining is a surface technique where workers clear vegetation, waste rock, and overburden from the ground. Typically, miners use these operations for extracting rock and coal from just below the surface.. Open-pit mining differs as workers excavate large landscapes on deeper slopes, separated by "benches."

Open-pit Mining
Open-pit mining occurs on surface and is generally the cheapest way to extract ore. This is because rock doesn't have to be moved far up hill against gravity, equipment used can be larger than underground, and it doesn't require more expensive features like ventilation, communications, etc. that underground does.
