Rock Slope Engineering Civil and Mining


A variety of engineering activities require excavation of rock cuts. In civil engineering, projects include transportation systems such as highways and railways, dams for power production and water supply, and industrial and urban development. In mining, open pits account for the major portion of the world’s mineral production. The dimensions of open pits range from areas of a few hectares and depths of less than 100 m, for some high grade mineral deposits and quarries in urban areas, to areas of hundreds of hectares and depths as great as 800 m, for low grade ore deposits. The overall slope angles for these pits range from near vertical for shallow pits in good quality rock to flatter than 30? for those in very poor quality rock.
