ChecklistGuro Drill and Blast Pattern Optimization
Maximize fragmentation efficiency and minimize operational costs with our Drill and Blast Pattern Optimization workflow. Engineered for modern mining management, this data-driven process streamlines blast design, enhances fragmentation consistency, and optimizes explosive distribution to reduce secondary breakage and downstream crushing energy consumption. Elevate your mine-to-mill performance with precision-engineered blast patterns.
Start
Start of the Workflow/Process.
1. Fetch Geological Survey Data
Retrieve rock hardness, density, and fragmentation data from the Geological Survey data model.
2. Retrieve Current Drill Inventory
Get data regarding available drill bits, diameters, and machine availability.
3. Calculate Burden and Spacing
Apply formulas (e.g., Kuz-Ram model) using rock hardness and explosive energy to determine optimal burden and spacing.
4. Calculate Powder Factor
Calculate the required ratio of explosive mass to the volume of rock to be blasted.
5. Create Proposed Blast Pattern
Generate a new entry in the 'Blast Pattern' data model containing the calculated coordinates and hole depths.
6. Update Site Constraints
Update the blast site status to 'Pattern Designed' to prevent overlapping work orders.
7. Assign Pattern Drilling Task
Create a task for the Drill Operator to execute the pattern based on the new design.
8. Retrieve Drilling Progress
Get data from completed drill logs to verify actual vs. planned hole depths.
9. Calculate Average Deviation
Aggregate drilling logs to find the average deviation between planned and actual hole positions.
10. Assign Blasting Task
Create a task for the Blasting Engineer to supervise the loading of explosives.
11. Update Pattern Status to 'Loaded'
Update the Blast Pattern entry to reflect that explosives have been placed.
12. Blast Notification Alert
Send an email to the Site Safety Officer and nearby stakeholders regarding the upcoming blast window.
13. Create Post-Blast Analysis Entry
Create a new entry in the 'Post-Blast Evaluation' model to capture fragmentation and vibration results.
14. Generate Optimization Efficiency Report
Generate a report comparing the 'Planned Powder Factor' vs 'Actual Results' to refine future models.
15. Finalize Pattern Record
Update the original Blast Pattern entry to 'Completed' and archive it.
