Open Pit Mining Pros & Cons Sciencing

Efficient OperationsOne of the major benefits to open pit mining is the increase in efficiency over deepshaft mining techniques. Because mining occurs at the surface, no space restrictions from narrow tunnels and shafts affect the rate at which ore can be extracted. Sampling each "bench" or level in an open pit before mining deeper makes it easy for surveyors to analyze the potential
