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."
