SMART TECHNOLOGIES SUPPORTING SAFE UNDERGROUND MINING

Edited by Leon Louw
Underground mines rely on smart technologies to gain greater understanding of their local geology and maintain safe working environments .

Experience has shown that rock properties change over time and each site is unique , requiring dedicated individual management .

A primary goal when undertaking large scale underground excavations is the protection of the workforce . Mitigating the risk of uncontrolled and unexpected rockfalls and protecting against future events is aided by smart technology solutions .
To minimise this risk , it is important to employ systems that constantly monitor the roof and sidewall conditions , especially in areas where high risk of failure has been identified .
3D laser scanners combine with state-of-the-art software to quickly provide a true understanding of the underground terrain , track movement and anticipate future events .
Data is important – capturing high resolution point-cloud data provides a firm foundation on which to develop realistic excavation

Leading global mining technology provider , Maptek , which celebrates 40 years in the industry this year , provides a complete solution covering convergence and deformation monitoring , design conformance , geotechnical and geological analysis , and reporting .
The Maptek solution allows for areas of risk to be identified from a safe distance using the laser scanner and geotechnical analysis tools . The same system is used for monitoring and alarming , providing consistency in data collection and confidence in reporting .
The custom-built Maptek SR3 underground laser scanner is at the heart of the solution .
Lightweight , easy to use and made to handle the rugged underground mining environment , the SR3 quickly collects
