Crushing plant layout differs a great deal from site to site. Plants are designed differently due to variation in the type of rock, the use of the products, the size of the quarry, plant history and many other factors. The plant model is formed by connecting the various production unit models to each other.
Rock slope failures pose significant challenges in geotechnical engineering due to the intricate nature of rock masses, discontinuities, and various destabilizing factors during and after excavation.
