Introducing the BMX Fragmenter

3GSM, a developer of software that optimises blasting and reduces inherent environmental issues, has launched BMX Fragmenter - new post-blast fragmentation analysis software that works as an independent module or seamlessly integrates into BlastMetriX UAV. BMX Fragmenter is described by 3GSM as a first-of-its-kind platform that automatically converts high-resolution drone images into a highly accurate 3D rendition of the muckpile with colour-coded delineation of gradation.

The system accepts overlapping high-resolution images taken by the operation’s standard drone. Using an interactive or pre-programmed flight plan, the flexible system leverages the drone’s GPS coordinates, so no ground reference markers are required. To save time and improve efficiency, the images remain local to the computer and do not require time-consuming uploading to the cloud.

The new BMX Fragmenter generates millions of 3D data points, reviewing an average rate of 200 photos per hour, for more complete statistical particle analysis. 3GSM says that what sets it apart from other programs is its automatic combination of 2D and 3D analysis for a more accurate and comprehensive evaluation of the muckpile surface.

A 3D post-blast model is automatically generated showing the width, throw and height of the muckpile. Particle sizes are colour-coded to give a quick gradation overview and for easy visualisation of oversized material. The system comes standard with editing tools for analysis refinement. Generated quantitative charts provide distribution of particle size and percent passing through the screen. Users can also assign fragmentation models like Rosin-Rammler, Swebrec and Swebrec extended to the analysis.

Results can be exported and saved in PDF format. The BMX Fragmenter also generates comprehensive summary reports to be used for blast program optimisation. In addition to open-pit mining operations, the new system can be used in debris flow, dam and underground applications.
