Drill & Blast Design Optimization
Optimize blast designs with geological analysis and regulatory-compliant engineering
What You Can Do
You can leverage Claude to analyze geological logs and rock mass data, calculate optimized drill patterns with precise burden-spacing, predict fragmentation distribution and muckpile behavior, and generate complete blast design documentation that meets regulatory requirements. Claude helps you explore trade-offs between fragment size and powder factor, assess environmental sensitivity, design perimeter control strategies, and troubleshoot previous blast performance to continuously improve outcomes.
Features
interprets rock type, RQD, UCS, and structural features to inform blast parameter selection
checks drill pattern geometry against industry standards and site-specific constraints
models expected fragment size distribution and muckpile behavior based on powder factor and hole spacing
explores cost-per-ton impact and performance trade-offs across different charge configurations
generates blast sequences to minimize wall damage and flyrock risk
produces compliance-ready blast design reports with full technical justification
recommends detonator delays to control blast direction and sequencing efficiency
analyzes previous results (vibration, fragmentation, oversize) to refine future designs
Example Output
Example 1: Burden-Spacing Optimization Input: Granite pit, RQD 65%, hole diameter 127mm, bench height 12m Output: Recommended burden 3.8m, spacing 4.2m, powder factor 0.85 kg/bcm, with fragmentation prediction showing 60% passing 150mm
Example 2: Perimeter Control Blast Input: High-wall adjacent to processing plant, sensitive structure 150m away Output: Reduced powder factor design (0.62 kg/bcm), staggered perimeter timing sequence, vibration modeling predicting <10mm/s at structure, regulatory compliance checklist
Example 3: Blast Design Troubleshooting Input: Previous blast produced excessive fines (40% passing 25mm), 2m flyrock event Output: Root cause analysis (excess powder factor 1.1 kg/bcm), revised design at 0.78 kg/bcm, modified delay timing, predicted outcome with 25% fines reduction
