To view the loaded state of your blastholes on the Insights portal follow the steps outlined in the following pages.
After navigating to your site from the BlastIQ landing page, select the “Blasts” icon on the left-hand side of the screen.
After selecting the specific blast you wish to view,
Select Hole Details – Loading, you will then be presented with an aerial view of your blast.
Aerial view of Blast - Loaded vs underloaded
There are 4 loaded states displayed
- Under loaded
- Within tolerance
- Not yet loaded
If however, there are multiple explosive decks in the hole and the top explosive deck does not have a weight recorded, then the hole will never be displayed in a fully loaded state.
Under normal circumstances, if the final stemming deck has been recorded as loaded the hole it will be considered loaded.
In the absence of a stemming deck being entered, BlastIQ will determine & display the loaded hole state using a calculation of “Scaled depth of burial”.
The scaled depth of burial is a calculation often used by engineers to indicate correct confinement of the explosive and optimal blast results that takes into account the hole diameter, the density of the explosive product and the length of stemming.
In areas where environmental constraints are tighter, a higher scaled depth to burial is recommended, whereas in less restrictive areas a lower scaled depth to burial ratio can be applied. To calculate the loading status, BlastIQ applies a conservative Scaled depth of burial = 2.
