New SR3 underground laser scanner

Staff reporter

PRESS RELEASE: The SR3 follows the extra-long-range XR3 and long-range LR3 scanners, which came onto the market in 2017. The R3 series is 30% smaller and 25% lighter, with 2.5 times faster data acquisition than the earlier I-Site 8000 scanners. Survey teams can work faster and smarter, with confidence that accurate, current topographic and volumetric data is guiding mine planning and geotechnical investigations, Maptek explained.

The SR3 laser scanner weighs 9.6kg and is accurate to 4mm. Surveyors will be able to measure stopes, drives and tunnels with ease.

High-resolution laser scans collect detailed data for geological and geotechnical face mapping. High-fidelity imagery captured underground at the same time as scanning provides context and support for analysis and communication.

A scan window of -40° to 90° vertically, and 360° horizontally captures all surfaces in any direction without the need for complicated configurations. Whatever the orientation of the scanner, integrated levelling automatically corrects scans before processing.

New functionality on the tablet controller allows users to import mine CAD strings and surfaces to view together with scans. This facilitates real-time comparison between the scans and allows users to compare this directly to the mine plan or geological models while underground.

A high rate of accurate data acquisition, ease of use, IP65 environmental rating and wide field of view for underground survey are notable system advantages. Modelling and filtering tools in the accompanying software are best fit for working with underground data.

Mine measurement product manager for Maptek, James Howarth, said: "A strong differentiator of our systems rests with efficient data processing. Mine professionals are always under pressure to do more within limited time-frames, so streamlined reporting is a compelling reason to use Maptek."
