Breakthrough Hatlestad

Breakthrough 1532 m. Hatlestad.

With a breakthrough for the 1530m long tunnel at Hatlestad over a height difference of 500 m, Norhard's former world record for drilling from below and up has been moved from 1030 m to 1530 m.

After the break through, the drill is now back and it is rigged for mounting of casing over a distance of 600 m in the lower part of the tunnel
