CHAPTER 11 Mining Technology Princeton

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,

Selection Of Mining Machinery
