Open Pit Mine Model
Open pit mining often results in a large hole, or pit being formed in the process of extracting a mineral. Deposits mined by open pit techniques are generally divided into horizontal layers called benches. The thickness of the benches depends on the type of deposit & the mineral being mined. Mining is generally conducted on a number of levels at any one time.
