    Types of MiningDevelopment of MinesMine ManagementMachineryDredgingUnderground mining occurs when minerals are deep below the ground. This is the most widespread method used for mineral extraction in Aotearoa, and involves digging a main shaft, with parallel shafts allowing the maximum extraction of minerals. The impacts to streams from this type of operation are frequently limited to those from transport and facilities associated with the mine, rather than direct mineral extraction. However, acid mine drainages have been observed in some cases where under...
