BlastIQ™ Insights – Dig Performance Monitoring Dashboard

This Knowledge Base Article describes the use of the Dig Performance Monitoring Dashboard in BlastIQTM Insights. 


Availability: This Dashboard is not supplied as part of the Standard BlastIQTM Insights offering.  It is supplied as an optional purchased add-on to the Standard Insights offering.



BlastIQTM Insights enables users to visualise the instantaneous (or pseudo-instantaneous) dig rates of mining excavation equipment (e.g. Shovels) within selected blasts via the Dig Performance Monitoring Dashboard.




To Dashboard

To navigate to the Dig Performance Monitoring Dashboard:

  1. From the BlastIQ™ Insights toolbar, select Dashboards.
  2. From the Dashboards menu, expand Blast Analysis and select Dig Performance Monitoring.



Within Dashboard

The Dig Performance Monitoring Dashboard is divided and arranged into three main areas:

  1. The Dashboard Header, containing the:
    • Blast Selection drop-down menu.
    • Graph Legend.
    • Map-tile Selection options.
  2. The Blast Map, displaying a plan view of the selected blast/s boundaries.
  3. The digging performance data

To view a blast:

  1. Click on the “Select a blast” drop-down menu found in the top-right corner of the Dig Performance Monitoring Dashboard to expand the selection list.select_blast.png

Blasts will appear in this list sorted by firing date (most recent first), then by Blast Name.

Unfired blasts are not available for selection on this Dashboard, only blasts that have been “fired” within BlastIQTM Insights are available for selection and display within the Dig Performance Monitoring Dashboard.  If a blast does not appear within the Blast Selection drop-down menu, check it’s “fired” status on the Blast Management page within BlastIQTM Insights, and set accordingly.


2. Select one or more blasts from the list of available blasts to view the dig data for that (those) blasts.


To change the base Map-Tile utilised in the Blast Map:

1. Select one of the available Map-Tile options found in the top-left corner of the Dig Performance Monitoring Dashboard. Five (5) different Map-Tile options are supported.


The Satellite base Map-Tile is displayed by default.


Pan and Zoom functions are enabled within the Blast Map:

  • Zoom In and Out is achieved by scrolling the mouse-wheel forward and back. Position the mouse over the area on the Blast Map of interest and scroll.
  • Panning the Blast Map is facilitated with a click and drag of the mouse. Perform a left mouse-click anywhere within the Blast Map, and whilst holding the click, drag in the direction you want to pan the view
  • Double-clicking the left-mouse button anywhere within the Blast Map view will reset the view back to the original default view state (i.e. a view zoomed and centred on the selected blast/s).


Pan and Zoom functions are also enabled within each of the individual Run-Charts:

  • To Zoom in on an area of interest within a Run-Chart, utilise a click and drag action with the mouse to define the region of interest to Zoom in on. Whilst holding the left-mouse-click and dragging, the region of interest will be highlighted within the view, upon release of the mouse-click, the view will update too the new zoomed extents.
  • To Pan the Run-Chart, depress the SHIFT key on your keyboard, whilst depressed use a click and drag action (SHIFT + left-mouse-click and hold) to Pan the view.
  • Double-clicking the left-mouse button anywhere within the Run-Chart view will reset the view back to the original default view state (i.e. a view zoomed to show extent of all available dig sample points for that blast).



Blast Map

Upon selecting one or more blasts from the Blast Selection drop-down menu, the Blast Map will render. 

Drawn on the Blast Map will be the blast boundary polygon for each selected blast. 


Each polygon is filled with solid colour, indicating whether there is digging data available for the selected blast or not.


A blast that has dig data recorded and available for viewing within BlastIQTM Insights will be coloured “green”.

A blast that does not have any dig data recorded and available within BlastIQTM Insights will be coloured “grey”.

A blast may not have any dig data available to display within BlastIQTM Insights for the following reasons:

  1. Excavation of the blast is yet to commence.
  2. Excavation of the blast has commenced; however, the data is yet to be received from the Customer Site’s Fleet Management System by Orica’s BlastIQTM When commissioning the Dig Performance Monitoring Dashboard an interval for, and timing of, the extraction of data from the Fleet Management System and subsequent transmission to BlastIQTM is agreed (for example, hourly on the half hour, or daily at 1:00am).  Dig data is not and cannot be streamed live from the Customers Fleet Management Systems to BlastIQ, only scheduled batch updates can be supported.

Hovering the mouse over a displayed blast polygon will reveal details of that blast including:

  • The blast’s name or identifier
  • The average instantaneous dig rate (observed to-date) for the blast, by Excavator type/model




Upon selecting one or more blasts from the Blast Selection drop-down menu, the Run-Charts will render. 

A separate Run-Chart will be displayed for each blast selected.  Each Run-Chart consists of a time-series scatter plot displaying each dig sample point observed during the excavation of the blast.  Each dig sample point is plotted based upon it’s time observed (x-axis) and calculated instantaneous dig rate (y-axis). 


Dig samples (for each blast) will be grouped and coloured by Excavator type/model.  If a blast has been mined using multiple, differing Excavator Types, then the run chart will contain multiple data series (one for each Excavator Type).


Hovering the mouse over a dig sample point on the Run-Chart will reveal details of that sample point including:

  • The date and time at which the dig sample point was observed
  • The calculated instantaneous dig rate for that dig sample point
  • The moving average instantaneous dig rate at that point in time. The moving average is calculated based upon the weighted average (by weight of the sample point) of all sample points within the preceding 2-hour period to the sample point of interest.  A moving average result is only returned if a minimum of five (5) dig sample points were observed within that 2-hour window.



Calculation of Instantaneous Dig Rate

Orica recommends the use of the Instantaneous Dig Rate measure for assessing the “diggability” (or ease of digging) of a muck-pile with respect to blasting effectiveness. 

This measure is preferred to other common measures of digging productivity, as it excludes many aspects of the dig cycle that are not influenced by the muck-pile presentation.  The dig cycle time components of swing, dump, and return, plus any other additional delay times within the overall loading cycle are excluded from the calculation of Instantaneous Dig Rate, the time component used in the calculation is the period from when the bucket engages the muck-pile, to when the bucket disengages from the muck-pile and starts to swing, and therefore is representative of the speed in which the Excavator bucket can be filled. 

Instantaneous Dig Rate is calculated as follows:



I = Instantaneous dig rate

P = bucket payload weight

t = bucket fill time

Most Fleet Management Systems provide the variables necessary to calculate Instantaneous Dig Rate. 

Some systems, however, do not allow for the provision of individual bucket weights, or do not break cycle times down into individual dig, swing, dump, and return components.  Where an Instantaneous Dig Rate measure cannot be extracted from the customers Fleet Management System data, an alternate digging productivity measure will be reported instead on the Dig Performance Monitoring Dashboard.  This will be advised during the commissioning of the Dashboard.  For this reason, BlastIQ users should not compare Instantaneous Dig Rate measures between BlastIQ sites, as the method for determining this measure may differ slightly due to differences in the available input data to the calculation.
