Earthwork and grading (or land shaping) in the reclamation phase of mining must take into account that the land will have been disturbed twice, once in the mining phase and again in the reclamation phase. Major disturbances to land creates complex reactions involving the geology, hydrology, soils, vegetation, land use, and the visual and aesthetic
Retaining walls are structure used to retain soil, rock or other materials in a vertical condition. Hence they provide a lateral support to vertical slopes of soil that would otherwise collapse into a more natural shape. Most common materials used for retaining walls are:
