Moranbah Mine Shaft

2 mine shafts (4 & 5) are drilled and reamed to approximately 30m below ground level at 4.3m diameter, using shotcrete as wall stabilisation cast in night shift. Shaft (6) is 7.8m diameter, which requires the construction of a “ringed hard soft secant wall” around the perimeter prior to internal drilling at 7.3m diameter down to 30m.
