Mixing of two mining system, selective mining by surface miner and main production by conventional method in the same mining block, shall compel using dumper transport for surface miner also. This will obviously reduce the productivity of surface miner.
Currently, the stripping ratio at active Minnesota iron ore (taconite) surface mining operations is at about 1:1. Based on the Biwabik Iron Formation's overall dip of 5 10° to the south in the area of interest, for every mile that mining progresses downdip, the depth to ore increases by about 700 feet.
