Jun 01, 2017· For pre-reinforcement of a 12-m long tunnel excavated in a weak rock mass, Hoek (2015) proposed the following solution: the grouted pipe forepoles would be 12 m long and 114 mm in diameter at a spacing of 0.3–0.6 m; the pipe forepoles would be installed every 8 m to provide a minimum of 4 m overlap between successive umbrellas.

Stability Analysis of Central Haulage in Baluba Copper

The research demonstrated that only 2.4 m grouted rock-bolts and timber sets is not enough in these conditions, so the 480 Level and 580 Level central haulage should be re-supported with a combination of 4.0 m pre-tensioned cable-bolts, a 75 mm layer of steel mesh (or fibre) reinforced shotcrete, and even steel arch sets with lots of log.
