Reclamation Of Surface Mined Coal Lands

Surface mining consists of the removal of the geologic strata overlying the coal seam usually with large electric shovels, draglines or bucket wheels. The method produces more or less parallel ridges or peaks of cast overburden, usually called "spoil banks". The mined lands vary widely in their inherent characteristics to produce a vegetative cover and thus can be put to a wide variety of uses. Use is the key to economic and social benefits. Physical and Chemical Characteristics of Soil Material of Surface Mined Lands after surface mining operations, the soil material is a heterogeneous mass whose physical and chemical properties are dominated by the character of the geologic strata overlying the coal. These strata are highly variable in thickness and character. They may include the surface soil, loess, glacial till, sands, shales, slates, limestone and sandstone rock. The method of mining with the several types of mining equipment will also affect the resultant mined area.
