INTRODUCTION TO MINING

If the excavation used for mining is entirely open or operated from the surface, it is termed a surface mine. If the excavation consists of openings for human entry below the earth's surface, it is called an underground mine. The details of the procedure, layout, and equip- ment used in the mine distinguish the mining method.
