Edit Blast Properties

NOTE: Please also note that settings vary between SHOTPlus Standard, Premier and Professional. The information in this article specifically relates to Premier.

 

When you edit any of the Blast properties using the Blast properties menu, these settings are saved and are only active for the blast design they have been set for. Should you choose to create a brand new design, these settings will be reset back to the default values set in the Program settings.

The current Blast properties can be stored in a new design template (File / Save as Template) and the settings edited in the Blast properties menu will be then available for a new project should you need. You can edit the Blast properties by clicking on Edit / Blast properties. You can now edit any of the blast options by selecting from the left-hand list in the dialogue. Each of these options provides its list of properties that can be adjusted to the given blast conditions.

  • You can edit the blast header information by selecting the Blast header information from the list on the left of the window. You can then edit the project header that can appear on selected reports. When you have finished editing click OK.
  • The blast header appears whenever you select the File / New option.
  • The blast header is also displayed in the Text file exporter. You can change it there if necessary by clicking on File / Export / Text file.
  • The new settings will only be applied to the project you are working on and be reset back to the default values set in the Edit / Program settings under Print titles.

 

Edit EBS Options

mceclip3.png

  • EBS options allow you to set the blaster type you are using and delay increments, as well as select options of timing offsets, hardware connections and uploads.

 

Edit Exceptions View Settings

mceclip4.png

  • The Exceptions view settings allows you to change minimum and maximum threshold values that appear on exceptions maps.
  • Water recharge: Allows you to alter the minimum and maximum threshold for water recharge, as well as the units, that you would like displayed on exception maps.
  • Powder factors: Allows you to alter the minimum and maximum threshold for Powder factor that you would like displayed on exception maps.

 

Edit Hole Type Settings

 mceclip5.png

  • The Hole types setting allows you to change the names of the hole types. The new names will appear throughout the program in dialogue windows in place of hole type 1 to 8.

 

Edit Initiation Settings

mceclip6.png

Initiation settings contain the following options:

  • Automatic tie flip: When this option is active, the direction of the surface ties will be automatically adjusted by SHOTPlus to reflect the correct propagation of the burn front.
  • Auto-connect echelons: When active, this option will attempt, where possible, to automatically fill the echelons with the delay you selected.
  • Colour ties: Toggles the colour and black-only option of the surface ties display. This option helps you to provide a more attractive print on black and white printers.
  • Visualize at collar: Shows the explosion animation at the collar only during the visualization process. If this option is not checked the explosion animation will be displayed at the centre of each deck. It is recommended to leave this option checked as otherwise, the blast animation of angled holes could be confusing.
  • Display nominal times only: If this option is selected, the system will display firing times using only the nominal delay. The nominal delay of detonators excludes the effects of propagation delay in the signal tube or detonating cord.
  • Show first in-hole time only: This option allows you to limit the hole timing displayed at the collar to only show the first detonator time per hole.

 

Edit Loading Chart Options

mceclip7.png

  • The loading chart option allows you to choose which information is displayed on the hole graphic in the loading tool window. It also allows you to choose which side of the graphic that some information is displayed.

 

Edit Loading options

mceclip8.png

The loading options settings contain the following options:

  • Surface tail length: This is the setting for extra length allowed for a surface tie. This extra length is then taken into consideration by SHOTPlus when determining the minimum required length product for connecting 2 collars.
  • In-hole tube wastage: This is the setting for the extra length allowed for an in-hole tie. This extra length is then taken into consideration by SHOTPlus when determining the minimum required length product for using within each blast hole.
  • Surface tube wastage: Setting for the extra length in percentages allowed for a surface tie. This is the additional amount added to the calculated quantity of cord products and an extra allowance required when selecting the correct product length of fixed length products.
  • Primer standoff distance: This is the setting for the standoff of a primer from either the top of the bottom of an explosive deck.
  • Use pillow decks: A pillow deck can be defined to provide extra standoff between the bottom of the hole and the primer position. When reporting charge weights and lengths, decks with similar explosive types are usually merged. A deck labelled as a pillow deck will appear on loading charts, even when the deck above has the same explosive type.
  • Use backfill tolerance: The backfill tolerance determines a minimum deviation between actual and design hole depths for which backfill will be added. With a backfill tolerance of one meter, the actual depth of a hole must be more than one meter longer than its design length before a backfill deck is added. The use of backfill tolerance turns this feature on.
  • Lock design length of dipped holes: Will lock the original design length for holes that have an actual length entered.
  • Include packaged products as primers: Includes packaged products in the primer resource list.
  • Include primer in charge weights: Adds the weight of a primer to total column weight. 

 

Edit Loading Rules

mceclip9.png

The loading rules options contain the following:

  • Back fill material: The program has stemming pre-defined as the backfill material
  • Alternative back fill: These program settings allow you to set an alternative backfill material.
  • Use alternative in segments A-B, C-D, E-F: This option is used in coal mines, and it conventionally assumes that coal is between A and B, C and D, E and F, and that the alternative stemming is to be used. Having this option ticked and two different types of backfill and alternative backfill selected allows the system to calculate volumes for each.
  • Dry loading buffer: The dry loading buffer above wet sides defines up to what level wet hole products need to be used and from what level above water dry hole products are to be used.
  • Mere dry loading above buffer: The merge dry loading above buffer option, if ticked allows the merging of the wet loading and dry loading above a certain distance above the water. Use the up and down arrows to define the dry loading buffer level above water.
  • Deck tolerance

 

Edit Material Types Settings

mceclip10.png

  • There are eight options for defining specific material types. Material types are the types of material to be blasted, and they tag the material to be blasted in a specific hole type. These material types are one of the parameters that need to be defined in the define hole default values window.
  • To name these material types, type their names into the respective fields. These new names will be seen throughout the program.
  • It is more often used to delineate different grades of the material being blasted such as high-grade ore, low-grade ore, waste, reactive etc. 

 

Edit Strata Definitions

mceclip11.png

  • Strata are geological domains where rock formations and coal seams are laid down in layers through which a blast hole is drilled. 
  • The intercepts are the borders at which the strata intersect with the hole. The standard Premier program allows for six intercepts and seven horizons, which are the layers of rock (white horizons) and coal or ore seams (grey horizons). Up to twelve intercepts are available with the appropriate extension key.
  • The intercepts are named from A to F, and the horizons are numbered from 1 to 7. You can rename each of the intercepts and horizons.
  • A colour can be selected for each coal seam.

 

Edit Summary Block Options

mceclip12.png

  • Select where the summary block is positioned on the page when displayed
  • Select what information to display in the summary block

Edit Surveying Options

mceclip13.png

The surveying menu is for setting the parameter values used by the SHOTPlus Profile wizard and the Mark out the wizard.

Profile tools are tools for working out what is in front of a hole and Mark out tools are tools for working out what the region around the hole looks like. Both of these tools allow the holes to be moved to some degree to optimize their position.

  • Move delta: This defines the step sizes by which you want to move the hole, either in small step sizes or in larger step sizes.
  • Angle delta: This defines the step sizes by which you move the angle of the hole, either by a small step or a large step.
  • Bearing delta: This defines the step size by which the direction of the hole is moved in degrees.
  • Step downhole: This defines the step sizes down the hole.
  • Search multiplier: When looking at the shape of the bench in front of the hole, face points are used to define the surface that is in front of the hole. To know what is in front of the hole, the search radius is used. The search multiplier is an internal setting that defines how many burdens are included in the search radius when trying to identify if there is a face point in front of the hole or not.
  • Perimeter overbreak: This defines the expected proportion of overbreak
  • Default collar RL: This value represents the default Z-value for the Profile and Mark out wizards.
  • Target heights 1, 2 and 3: These define the values for the laser survey tool stick sizes.

 

Edit Volume Calculations

mceclip14.png

  • The program gives you two options to calculate volumes as starting values for new blasts:
    • Option 1 is for the calculated blast hole volumes to include design burden and spacing only,
    • Option 2 is for the inclusion of sub drill in the blasted volume.
  • Tick the appropriate checkbox and then OK and the program will from then on calculate blasted volumes according to your selection.
  • Select if you want to include sub drill in the calculation and design burden and spacing
