The method of preparing an underground ore body for mining is similar for all iron mines. The shaft is sunk adjacent to the ore body to a depth below the ore to be mined. At predetermined intervals along the shaft, normally every 200 feet, tunnels called drifts and crosscuts are driven from the shaft to the ore body.
