DRILL & BLAST


A


tlas Copco has launched a new piece of automation software for drill rigs. T e design enables the rig to create


its own drill plans directly at the material face. T is is made possible by downloading the contours of the mine drift (or tunnel) with a drill rule fi le, allowing the machine to tailor its own plan specifi cally for the circumstances it is facing. So rather than importing the 3D mine model into software such as Underground Manager then manually creating the drill plan, the set of rules and the 3D model are input to the drill rig by USB or WiFi. T e rig will then make its own drill plans. One advantage is that this mitigates


problems caused by diff erences in rock or soil cross-section. Johan Jonsson, global product manager - Face Drilling Equipment (Boomer-range) tells IME, “T is dynamic tunnelling package will greatly simplify and reduce the waiting time in many mine and tunnel projects globally. By also creating the drill plan for the actual section where it’s navigated, the quality will be improved at the same time.”


Several trial projects have been used to test the new software, including one with Atlas Copco’s customer Veidekke, which is working on the State highway 80 project in Bodø, Norway, removing about 500,000m3


of rock to create


two 2.5km tunnels. Jon-André Nilsen, manager Surveying Technic Underground for Veidekke comments, “T e collaboration with Atlas Copco to develop the dynamic tunnelling package went well. T ey were responsive to our feedback and made adjustments to the program. Today, the drill rig operators make niches manually. T ey can turn out way too big or way too small. T e dynamic tunnelling package makes our drilling more precise. We can make changes to drill plans directly on the rig. We can move cuts or drill holes. We are more fl exible at the tunnel face compared to making all the changes at the offi ce. We use the software to make niches. T is makes the work more precise.” Kent Simensen, drill rig operator, adds, “T e dynamic package is very easy to use. It is two keystrokes and you are started. T e contour turns out very accurate. T e end result is identical to the drawing.”


MITO YOU F


raste, hailing from Nogara in Italy, is launching a


new hydraulic rig called the Mito 8. Featuring the Fraste articulation system, the machine is off ered with a wide range of accessories available for rotation and roto- percussion drilling.


The new drill expands the


Mito range that includes the larger Mito 20, Mito 40, Mito 60 and Mito 40 CS. ●
