TLC Hole Signature Analysis

Optimize Blast Timing with Confidence

TLC Hole Signature Analysis (HSA) is a precision blast engineering tool designed to reduce ground vibration and improve blast performance through signature hole analysis. Whether supplying data from a seismograph or building a pattern from scratch, HSA gives blasters the analytical tools to optimize timing, manage blast designs, and export results for regulatory compliance and reporting.

Signature Hole Analysis

Perform detailed signature hole analysis on blast patterns using real-world seismograph data.

• Import signature hole data from any seismograph manufacturer
• Supply blast design data via CSV or create a blast pattern directly in the software
• Input hole loads and timing for full pattern control
• Support complex designs with multiple hole decks

Timing Optimization

Generate optimized blast timing designed to reduce peak particle velocity (PPV) and manage frequency response at sensitive locations.

• Automatically generate optimized timing delays
• Reduce PPV and control frequency at sensitive locations
• Analyze waveform superposition across the full blast pattern
• Support complex, multi-deck blast scenarios

Blast Design Database

Store and retrieve blast designs and signature hole records for future reference, compliance documentation, and design refinement.

• Database blast designs and signature hole records
• Access saved designs at any time for review or reuse
• Maintain an organized history of site-specific blast data

Export and Reporting

Document and share optimized timing designs in the format that works best for your existing workflow.

• Export optimized timing designs as CSV, PDF, or Excel
• Generate professional reports for regulatory submittal
• Integrate results into existing blast documentation processes

K Factor Regression

Perform K factor regression analysis using existing blast monitoring data to improve site-specific vibration predictions.

• Derive site-specific K and n attenuation constants
• Use regression results to improve future PPV predictions
• Base blast planning on data from actual site conditions

How TLC HSA Fits Into Your Workflow

Use TLC HSA to move from raw seismograph data to an optimized, documented blast timing design. From signature hole import through final timing export, HSA provides the analysis needed to manage vibration limits while protecting surrounding structures and communities.
