  • Open-pit mining - Wikipedia

    Open-pit mines create a significant amount of waste. Almost one million tons of ore and waste rock can move from the largest mines per day, and a couple thousand tons moved from small mines per day. There is generally four main operations in a mine that contribute to this load: drilling, blasting, loading, and hauling. Waste rock is hauled to a waste dump. Waste dumps can be piled at the surface of the active pi

    Open Pit Mining. Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.
