SYNOPSIS. Rock has been cut in the process of mining since before the invention of explosives. Today, we seek to return to cutting to reap the benefits of continuous operations for South African underground hard-rock mines, to improve speed of access to the orebody, and to improve the efficiency of mining operations.
The Annual Breakthroughs in Tunneling Short Course covers all aspects of conventional and mechanized tunnel design and construction in hard rock, soft ground and soils.
