Open Pit Mining Open-pit mining is a kind of surface mining. Mining companies choose this way to get rocks and minerals out of the ground because it is the easiest and cheapest way to do it. Open-pit mining is only used if the rocks or minerals are close to the surface of the land or if a normal tunnel-type of mine isn’t possible. The top layers of the land are removed. After that‚ layer after layer is taken away until the rock or mineral is visible. This is taken out‚ processed when it

There are several forms of mining that are used to extract minerals and rocks from layers of earth and open-pit mining is one of these methods. This method uses a borrow or open pit and is most frequently used in situations where the desired rocks or minerals are located close to the earth’s surface. A. The Structure of the Open-Pit Mine An open-pit mine is structured in steps‚ often also termed “benches‚” which are the pit’s vertical levels. These steps commonly range from four to sixty meters
