Blasthole Loading Summary

Note: This applies to charging licenses only.

The loading summary screen gives you a graphical representation of the overall loading state of a blasthole, along with a summary of each deck's properties. Tap on a deck to select it.

The toolbar buttons at the bottom of the screen will perform the following actions:

dp2.png Zoom into the hole diagram

dp3.png Zoom out from the hole diagram

dp4.png Move the deck selection up the blasthole

dp5.png Move the deck selection down the blasthole

dp6.png Dip the blasthole (i.e. show the dipping data entry screen for this hole)

dp7.png Turn Design view on or off (see below)

Hole Diagram

The diagram on the left shows you the deck, primers and strata intercepts within the hole. You can tap on a deck and select it and it will be outlined in red. Alternatively tap the dp4.png or dp5.png buttons to move the deck selection up or down the column. 

If a deck has been loaded, it will have a green background visible in the right-hand half of the red outline. If a deck has been flagged as incomplete, the green background will be striped.

Grade RL is indicated by a horizontal dotted line across the whole width of the diagram.

If you have zoomed into the diagram, you can pan it up and down by dragging it with the stylus or your finger. To see the entire blasthole again, tap on Menu / View / View All.

Tap on a primer (yellow rectangle) to see more information about it, such as detonator and booster type, depth and primer count.

The name of the loading rule (if any) which created the loading design for the hole is shown below the hole diagram.

If strata or coal seams have been defined for this hole, they will be shown on the hole diagram as grey bands behind the depth scale.

Tap on a stratum or an interburden (the white striped regions between the strata) to see more information about it, such as timing horizon name and top and bottom surface depths.

Note: Strata intercept depths can be set on swipe page 5 of the dipping data entry screen, or in SHOTPlus's 'Edit hole' window on the Strata/Profile tab.

 

Design or Actual View

Tapping the dp7.png button on the toolbar lets you toggle between the current as-loaded state of the blasthole and the original loading design that was produced by SHOTPlus. This lets you make a visual comparison between the blasthole's design and actual charging state. Alternatively, you can choose Menu / View / Design View to turn design view on or off.

Design View is read only. You cannot enter any loading data when Design View is active.

To exit Design View, tap dp7.png again.

In Design View, the diagram shows the original loading design as it was produced by SHOTPlus (i.e. ignoring any actual loading data and hole re-dips).

Note: If loading rules have been applied to actual dip depths, and the dipped depth of a hole is less than the design depth, then the original design of the hole will be shown as a dotted outline (as in the below screenshot).

Value Status Flags

At the right-hand side of the screen are four status flags, one for each of the following deck properties:

  • Charge weight (for bulk products) or cartridge count (for packaged products)
  • Top of deck
  • Bottom of deck
  • Deck length

The flags have the following meanings:

dp12.png Design: The property has not been measured. The displayed value is the design value obtained from SHOTPlus (e.g. from loading rules or manual loading).
dp13.png Adjusted: The property has not been measured but its value has been automatically adjusted from the design value by DIPPlus because either (a) the deck below has been over- or under-loaded, or (b) the hole has been re-dipped and its depth has been changed since the loading rules were applied. 
dp14.png Actual: The property has been measured or its value can be deduced from other measurements. The displayed value is the actual as-loaded value of the property.
dp15.png Unknown: The state of the property is none of the above.

 

 

Next/Previous Holes

The Next and Previous buttons take you to the next or previous blasthole in the set of holes to be loaded. If you tapped on a hole on the loading path, or if you selected the 'Load Holes on Path' menu option, then the Next and Previous buttons will step along the path one hole at a time. If you're loading a single hole then the Next and Previous buttons will be disabled.

 

Loading a Deck

Tap the 'Load This Deck' button to enter loading information for:

  • Any unloaded deck, or
  • The highest loaded deck in the blasthole (for example in cases where the product in the deck has slumped or risen and you want to enter subsequent measurements of horizon or additional charge weight). In this case the caption on the button will be 'Top Up This Deck'. 

This will take you to the charging data entry screen.

 

Blocked Holes

To indicate that a blasthole has collapsed or is otherwise unserviceable, you can mark it as blocked. You can set the blockage at a specific depth or you can set the blockage at the hole collar.

 

BLOCKAGE AT A KNOWN DEPTH

To indicate that a hole is blocked at a specific depth, hold the stylus or your finger down on the hole diagram at the approximate depth of the blockage. Then choose 'Set Blockage Here' from the popup menu.

Confirm that you want to mark the hole as blocked.

A blockage is indicated on the blasthole diagram by a thick black line across the hole, and on the blast plan by a brown ring around the hole. Decks below a blockage cannot be loaded.

dp16.pngTo remove a blockage at a specific depth, you must reset the charging state of the deck in which it was created. This deletes all charging measurements for the deck. This operation cannot be undone.

For example, to remove the blockage in the example above, you would select deck 2 and either choose Menu / Edit / Reset Deck 2 or hold your stylus or finger down on deck 2 and choose 'Reset This Deck'.

 

BLOCKAGE AT THE COLLAR

To indicate that a hole is blocked at its collar, hold the stylus or your finger down on the hole diagram and choose 'Block At Collar' from the popup menu, or choose Menu / Edit / Block At Collar.

Confirm that you want to mark the hole as blocked.

The hole state will change to BLOCKED and no decks will be loadable.

To remove a blockage at the hole collar, choose 'Unblock At Collar' from the popup menu or the Edit menu. (Alternatively, you can reset the charging state of the top deck in the column, but this will also delete all charging measurements from that deck as well as removing the blockage.)
