Versatility of Machines and Attachments Lead to Increased Use in North America. By Karl H. Mitterndorfer. The need to understand the rock cutting process in an intensive way has become more and more of a necessity due to the various options using mechanized excavation and tunneling methods.
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.
