Fragmentation Analysis and Report

Fragmentation Analysis

This is a tool for blast fragmentation analysis. It is an automated detection — and analysis of rock sizes from muck pile scans.

Takes a point set of a pile of rocks and breaks down the points into individual rocks and then graphs the resultant distribution of fragment size against the term "% rocks passing sieve".

  1. Select the stock pile needing analysis.

  2. On the Query ribbon tab navigate to the Fragmentation Analysis group and select Fragmentation Analysis.

  3. Select Manual scan origin and pick a point in front of the data set.

    Important: This is required if there are multiple scans used or a non-scan point cloud data is used for the analysis.

  4. Choose an output destination.

  5. Click OK.

    PointStudio will analyse the fragmentations and export the results into the destination folder.

    Note: Each time the tool performs an analysis it will iterate the results to the output location.

    Rocks can be randomly coloured according to different sizes with Ctrl + 2 for a better visual representation.

  Find a large sample rock and measure its width to be used in the reporting set up panel. Find a small sample and measure its width to be used in the reporting set up panel.
 

Fragmentation Analysis Report

Following a Fragmentation analysis, selecting Fragmentation Analysis Report will generate a report including images and graphs that can then be exported to PDF or a CSV format.

  1. On the Query ribbon tab navigate to the Fragmentation Analysis group and select Fragmentation Analysis Report.

  1. Drag the fragmentation analysis of selection container into the Fragmentation results container field.
  2. Click inside the Legend field and click to select the Fragmentation analysis legend which is found in the Legends container.
  3. Select Colour points by rock size to colour the rocks according to the legend description.
  4. Select Show overview image to display a colourful representation of the selected area in the report.
  5. Select SWEBREC curve fit to display the fragmentation size distribution in a graph.
    • Select the Experimental: Re-estimate xMax to enable Experimental: Limit parameter b
    • Enter the measurements calculated earlier.
    • From the drop-down list select the way to represent the findings in the graph.
  6. Select Custom mesh sizes (mm) to report the quantity of rocks found below the dimension set (in %)
  7. Select CSV export option if a csv is required and assign the Destination path for the ffile.
  8. Click OK or Apply.
     A report on the fragmentation analysis will be generated. 

    Below is an example of the Fragmentation Analysis report (first part) graphically displaying the rock sizes and coloured according to the legend.

    Example of the Fragmentation Analysis report (second part) that displays the following:

    • Fragmentation size distribution as a SWEBREC fit graph and the parameters used for it. (If selected)
    • A Decile percent passing table showing you the percentage of rock sizes found. (If selected)
    • A Custom mesh passing table showing you what percentage of rocks will pass through a custom mesh size. (If selected)

    The report can be downloaded by clicking and or printed by clicking .
