CHAPTER 11 Mining Technology

Surface Mining Techniques Surface mining of coal is characterized by the use of large, capital-intensive and effi-cient mining equipment. First, the overlying soil and rock layers (overburden) are re-moved. The coal is then fractured with explo-sives or machines, and loaded onto vehi-cles for haulage from the mine site. Finally,

Equipment Selection for Surface Mining: A Review

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.
