Ok Tedi Mine
In 2012 Ok Tedi was our first installation of a 200m+ surface-down raise bore Laddertube escapeway.
The Situation
The Ok Tedi mine is 100% PNG owned. Ok Tedi Mining Limited operates the longest-running open pit copper, gold and silver mine in Papua New Guinea, with 100% of the benefits from it’s operations are distributed to the people of Western Province and the State.
We fly into Tabubil township, which is the largest settlement in the province and about 20km south from the mine site.
The Solution
The original Safescape installation took place in 2012, with the initial 201m x 1.1m diameter raise bore being installed from the pit (surface) down, and at that time was the longest, and the first of now many surface-down Safescape installations here and around the world.
Access into the underground workings is into the side of the mountain via rail with several Locomotives.
In November 2021 we installed another 200m escapeway from the surface down to the underground workings. This had a break through at the 169m mark and the top of the escapeway was then covered off to prevent any damage or injury from any surface works being undertaken.
The Outcome
The Ok Tedi surface-down Laddertube installation in 2012 really paved the way for one of our most popular use-cases.
