Issue Underground mining, by its nature, presents a range of health and safety hazards that are different from those in other sectors. Some hazards, such as ground instability, are inherent in the underground environment. Others are introduced through complex
Copper ore is mined in our X41 and Enterprise underground mines, where it is roughly crushed, then hoisted to the surface for processing. From here, it is fed through a series of ball mills that grind the rock into a fine dust. This dust is then mixed with water and
Mining mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on
