Open Pit Mining Techniques|Surface Mines|Rock or Mineral
Open Pit Mining Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow The word is used to distinguish this type of mining from extractive methods that need tunneling into the earthOpen pit mining refers to mining directly on the ground surface, thereby producing an open pit This method is practical and costeffective when the uranium ore is located near the surface (eg, within 100 m) Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depthsOpen Pit Mining an overview | ScienceDirect Topics
