2. To make viewing the holes you are loading easier, Isolate the ring or group of rings you would like to load. A good practice is having rings grouped in the Ring Manager. The layer and visibility manager tools can be used to hide other objects which could clutter the screen.

A yellow collar indicates the blasthole has no loading designed assigned to it.

4. Manual hole loading.

To add a deck select Add After or Add before to insert a deck to the hole.

Select the required explosive or material from the drop-down list.

Select which deck you would like to have varying length by clicking on the deck then the double red arrow button below

Adjust any non-varying decks in the length column.

You will notice your varying deck will grow or shrink to maintain the overall hole length. This is due to the variable deck tool being assigned to the explosive deck as shown below.

Primers can be added by first selecting the product deck for which you wish to prime, then click the Add button at the bottom of the window. Select the detonator then booster.

Place the primer at the desired position within the explosive column using your preferred method. Choose from the three defined positions top middle or bottom of the deck (the top and bottom use a standoff distance set in Blast Properties. The user can also position the primer at a point which is a % of the hole length measured from the bottom of the hole.
