Ore Scanners

Each ore scanner is equipped with two scanner heads and a distance sensor, which is mounted above a scanner bay. Each scanner head has a high-grade and a low-grade detector, and the appropriate detector is auto selected based on count rates. Each scanner also has a test source for each detector, that are used to check the functionality of the detectors. The results of each scanner head are averaged by the system’s software to determine the ore grade category, which is displayed for the equipment operators and also saved to file.

Since the same hardware is used for both truck and scoop scanning, the hardware is interchangeable for all of a site’s ore scanners. This provides an additional level of redundancy if there is a failure in a component of the system, especially for remote sites. The system can also run in single head mode, which adds to the system’s redundancy.

The ore grade thresholds are user configurable using a Windows based interface program installed on a PC mounted in the main enclosure. Text and .CSV files are created for the results of scans, background tests, and detector tests. Scan results include date, time, stope number and equipment (truck/scoop) ID, ore category, cumulative counts for each detector, distance measured from load to detector heads, and averaged distance compensated (if selected) cumulative counts. User specific output formats are also possible.

Remotes can be coded with an equipment number to identify the truck/scoop by the scanner software.

Optional sensor(s) and a traffic light system can be installed for proper equipment positioning.
