Laser Scanner for Underground Survey

Maptek, the Australian provider of innovative software, hardware and services for the global mining industry, has released a new laser scanner designed specifically for underground applications. The versatile I-Site 8200 can be coupled with a range of accessories to provide a complete scanning system for underground drives, tunnels and stopes, as well as surface stockpiles and silos. Processing of scan data can be undertaken in I-Site Studio and I-Site Void software.

The I-Site 8200 has all the characteristics of I-Site systems - speed and accuracy of data collection, portability and rugged industrial design. In demanding underground operations the focus is on safety and ease of setup, requiring comprehensive scan coverage and getting an accurate model in the fastest time possible.

The I-Site 8200 has a scan window of -35 to 90 degrees vertically and 360 degrees horizontally. Whatever the orientation of the scanner, integrated levelling automatically corrects scans before processing.

The signature discriminator for I-Site scanners has always been workflow. Maptek manager of Laser Scanning Solutions, Athy Kalatzis said that coordinated development of all the elements - scanner, accessories, scan control interface, and processing software - allowed Maptek to ‘build in’ the underground workflow from the outset. Maptek talks to its customers, the extendable carbon fibre boom, hatch bracket and vehicle mounts have all been designed following trials and feedback, Kalatzis added.

The boom extends up to 10 metres into a tunnel or over a void, and the quick-release mechanism allows the scanner to be easily removed. The 3D view of the scan on the controller helps the surveyor or geologist see inside the stope.

Maptek scanning systems are purpose-designed, but maintain a level of operational flexibility. A surveyor might move from underground stopes to above ground stockpiles in the same shift. The I-Site 8200 laser scanner is versatile enough to handle the transition, Kalatzis continued.

The I-Site 8200 is rated to IP65. Australian field trials proved the scanner’s reliable operation in the underground environment. Users can safely scan underground, and survey inaccessible or dangerous environments, said Kalatzis. The I-Site 8200 can be mounted on a vehicle underground to survey drives, and tailor the instrument for specific applications such as pre and post shotcrete fill.

Maptek also produces I-Site 8810 and 8400 laser scanners which target long-range survey applications.
