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,
Shovel and Dumper Combinatio by Auqib Javed.pptx
Education. Shovel and dumper combination is a type of heavy equipment used in open cast mining operations. It is composed of two separate machines, a front-end loader (shovel) and a backhoe (dumper). The shovel is used to scoop ore, rock, or other materials out of the mine, while the dumper carries the load to a designated area for …
