Thirty-three men, trapped underground and from the mine's entrance via spiraling underground ramps, were rescued after 69 days.

Beaconsfield Mine collapse halted blasting in the access tunnel, and instead drilled a smaller hole through the approximately 14.5 metres of rock between the head of the access tunnel and the part of the side tunnel where the miners were trapped. Webb and Russell directed the work by listening to the sound of the drilling and judging the direction. The hole was about 90 millimetres in diameter. A PVC pipe was used to line the hole, which was used to deliver fresh water, food and communications equipment to the men. On 1 May 2006 rescuers were still 12 metres from the miners. They
