How to set up drill scheduling in a production model.
Introduction
Drill scheduling introduces delays relating to blasted stocks, available real estate, and fleet logistics.
...
Finished plans may be published as a colour-coded drill plot for issue to 48-hour planners.
Workload
Drill scheduling requires preparing, importing and using data in addition to the existing production schedule workload.
...
- Enter drill meters remaining in half-drilled shots.
- Enter number of drills operating in a pit, stage or bench.
- Enter manual drill sequences at the bench level (if required).
Setup Procedure
Step by step guide to set up drill scheduling in a production model.
Rapid Reserver
In Rapid Reserver, add the blast properties which will affect drilling.
...
Choose blast properties that are appropriate for your site.
Blast Tags
Configure the block tags in Rapid Reserver > Designer tab > Display menu.
...
- Blanks will be assigned default blast parameters (ie. medium hardness, production shot).
- Blocks labelled "Blasted", "FreeDig", or "Backfill" will be assigned zeroed blast parameters.
Tactical Scheduler Setup
Configuration Options
In Setup > Configuration Options, select 'Use Drills' to turn on Drill Scheduling.
Extension Source
In Setup > Extension Source, select the Site Specific Extension that has been provided by Alastri. The extensions hold the logic for populating block-by-block drill quantities from user inputs.
Misc Fields
In Setup > Misc Fields, create new Misc Fields to classify the blast blocks:
- Surface Area
- Presplit Perimeter
- Blast Status
- Hardness
- Rig Type
Drilling Fields
In Setup > Drilling Fields, add reporting fields such as number of holes, length, volume, and so on.
Drill Hole Types
In Setup > Drill Hole Types, add the hole types that will be encountered in the project.
Map Fields
Map the reserves values into the new Misc Fields.
Refinements
In Setup > Refinements, parameter input tables are displayed for every hole type that is detected in the reserves. Enter the appropriate parameters for each hole type.
...
Blast parameters and calculation methods may be configured in the Site Specific Extension.
Drilling Dependencies
In Setup > Dependencies > Drilling, enter the dependencies to be used in each mine, pit, stage or bench.
...

|---|
| *Blasting Delay can be made a variable in the Site Specific Extension if required. |
Drill Types
In Setup > Drills, add the drill rig types to be used in scheduling.
- Tick the availability types to be added as rows in the Calendar.
- Tick the hole types that can be drilled by each rig type.
Incentives
In Setup > Incentives, add priority incentives to store the drilling sequence for each pit.
Constraints
In Setup > Constraints, add constraints to control blast stocks limits, drilling meters by pit or bench, and drill unit assignment by area.
- Constrain stocks blasted in the period with a Standard Constraint on drill volume.
- Constrain number of each drill type by pit or bench with an Agent Assignment Constraint.
- Constrain drill quantities by pit or bench with a DrillSource Constraint.
Schedule Calendar
Drills
Enter the total number of drills and time usage by period.
...
| Info |
|---|
Priority Incentives are defined in Setup > Incentives. The manual sequence is entered in Schedule > Animation > Priority Incentives. |
Constraints
Enter the values by period in each constraint.
- Constrain stocks blasted in the period with a Standard Constraint on drill volume.
- Constrain number of each drill type by pit or bench with an Agent Assignment Constraint.
- Constrain drill quantities by pit or bench with a DrillSource Constraint.
Priority Sequencing
Go to the Animation tab and find the Priority Incentives panel in the top left corner. At the beginning of the schedule, edit the priority incentive for each pit and pre-assign the drill sequence for the entire pit. This way, whenever you assign a drill to this pit in Calendar > Constraints > Drill Assignments, it will pick up the sequence where the last drill left off.
