Rescue workers in Chile’s San Jose mine have reinforced an escape shaft to hoist 33 miners trapped underground for over two months.

The rescuers have successfully drilling a 625m shaft that will be used to evacuate the miners.

Mining Minister Laurence Golborne said the government aims to start the evacuation on Wednesday, and it could take up to two days to hoist all 33 men to the surface.

Golborne said the steel casing of the shaft is expected to be completed by today followed by the assembly of a winch-and-pulley system above the shaft before a capsule, named Phoenix, can be lowered to the trapped miners.

The miners have been trapped underground since 5 August when a partial collapse blocked the exit to the San Jose mine in the Atacama desert.
