Real-time Rock hazard identification on the face can be improved through georeferenced scans and topographical correction for intuitive structure identification
About
1. Georeferenced scan data Georeferenced scan data is the ability to attach the location of scans recorded with reference to the mine's local coordinate system. This makes it easier to manage and understand the recorded data, resulting in improved communication of hazards and a safer work environment. 2. Topographical correction Topographical correction is required where rock surfaces underground are not always flat or even, and do not follow the geological structures being observed. Topographical correction accounts for undulating rock surfaces and allows for the plotting of structures in a true and continuous form. Topographical correction creates a virtual point of reference which gives preference to the geological structure being observed.
Key Benefits
1. Increase in efficiency Being able to know the exact location and time at which the SSP data was recorded, develops better data management. Improving the workflow of how data is managed allows for a more effective use of data and how it can be applied. 2. Reduction in operational cost With efficient data management and planning there is an opportunity for a reduction in operational costs. The accurate identification of sub-surface rock mass structure in real-time, results in immediate decision-making on the working face. 3. Improved safety The SSP offers real-time rock hazard identification. The adoption of the SSP is improved when the workflow of scanned data is better managed. The identification of rock mass hazards is made clearer when the changes in rock surfaces are accounted for in the scan through topographical correction.
Applications
Ground penetrating radar for use by underground mine personnel to investigate and identify rock mass hazards in the face area or in re-entry of old working areas.
