Underground Mining Processs

Underground Mining Underground Mining is generally used for areas where the mineral seam is too far underground for open cut mining to be of use A tunnel called a decline is created to allow workers and machinery to reach the location of the minerals Stope mining is used for most hard rock mining of minerals such as copper silver lead
