Mar 08 32 These surface mining methods are considered to be more efficient and economical in extracting minerals as compared to most methods of underground mining In fact it can extract almost 90 of ore from a deposit For this reason surface mining is Mining Mining Surface mining It has been estimated that more than two thirds of the world’s yearly mineral production is extracted by surface mining There are several types of surface mining but the three most common are open pit mining strip mining and quarrying These differ from one another in the mine geometries created the techniques used and the minerals produced

A new variation of open cut mining high wall mining is not strictly a surface process but instead a combination of surface and sub surface mining The process is also predominantly a coal mining technique which has been employed successfully in Kentucky and West ia in the United States and also in Queensland AustraliaPrincipal considerations in the selection of surface mining and reclamation techniques and equipment include the thickness and character of the overburden the dip of the seam the thickness and number of recov erable seams and the physical and chemical characteristics of the coal The three surface mining techniques most widely used in the
