3GSM releases first real 3D muckpile fragmentation analysis

Software developer 3GSM has unveiled its new BMX Fragmenter, which combines 2D and 3D fragmentation analysis to improve accuracy from drone imagery for a fast and fully automated analysis of an entire muckpile.

3GSM GmbH, with offices in Ohio and Australia, has released the new post-blast fragmentation analysis software BMX Fragmenter to work as an independent module or a system that can seamlessly integrate into BlastMetriX UAV.

“BMX Fragmenter is a first-of-its-kind platform that automatically converts high resolution drone images into a highly accurate 3D rendition of the muckpile with color-coded delineation of gradation,” the company explained.

“The system accepts overlapping high-resolution images taken by the operation’s standard drone. Using an interactive or preprogrammed 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.”

BMX Fragmenter has the capability to generate millions of 3D data points, reviewing an average rate of 200 photos per hour, for more complete statistical particle analysis. It also automatically combines both 2D and 3D analysis for a more accurate, comprehensive evaluation of a muckpile surface.

“Delineation using only 2D analysis can lead to inaccurate measurements due to shadowing and the particle’s contour and structure,” said Robert McClure, president of Robert A. McClure (RAM).

“Adding the third dimension offers more accurate delineation through shape, and the 2D analysis is used for refinement and smaller particle detection.”

A 3D post-blast model is automatically generated showing the width, throw and height of a muckpile. Particle sizes are color-coded to give a quick gradation overview and for easy visualization of oversized material.

3GMS said its system comes standard with editing tools for analysis refinement; quantitative charts generated 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, and summary reports can be generated for blast program optimization use.

In addition to open-pit mining operations, the new system can be used in debris flow, dam and underground applications.

The 3GSM product portfolio includes the BlastMetriX and ShapeMetriX product families.
