These factors inherent in ore deposits in ways largely determine the development and utilization. Depth of burial is decided Deposits opencast or underground mining. In general the cost of open-pit mining is lower than underground mining. But this is not always the case, It depends on the specific conditions of occurrence deposits. Deposits although some shallow due to a large amount of stripping rock, its cost is not economical than underground mining, have mined using underground. Of course, some deposits in buried deep underground mining would only be
