It was initially predicted that the void left in the conglomerate at Moonee would span 100m and the roof would fall in “small lenticular shaped pods”.
Instead in the first goaf (roof) fall in the Moonee panel, an area up to 14m high and with a mass of 20,000m2 was involved. This created a wind in excess of 360 km per hour and it damaged machinery and equipment.
A second fall knocked over and injured 6 of the 19 men working in the area. Although the injuries were relatively minor the incident had a significant psychological impact.
