However, drill rigs in the mining industry have very limited adoption of OEE as a good performance indicator. The concept of OEE and its application has not been fully realised in the use of drilling in the mining industry. Drilling is the initial step in hard rock open-pit mining. It goes hand-in-hand with the blasting

There are two types of benches in each open pit mine: working benches and safety (catch) benches. Working Benches. Working benches are where unit operations (drilling, blasting, loading, and hauling) are performed. Working benches are wider than safety benches to provide enough room for the mining equipment to perform their tasks. Safety (Catch ...

Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the ...

Open-Pit vs. Strip 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 Pit geometry. Deposits mined by open-pit techniques are generally divided into horizontal layers called benches. The thickness (that is, the height) of the benches depends on the type of deposit, the mineral being mined, and the equipment being used; for large mines it is on the order of 12 to 15 metres (about 40 to 50 feet).
