Dust & DPM — Drill Dust Capture Check
Drill Dust Capture Check for mine air quality management.
A single dry-drilled hole can shed more respirable silica than a week of wet drilling — capture efficiency is everything, and the difference between 95% and 99% is 5× the dose. This mass balance shows why drill-rig water systems get fixed TODAY, not at the next service.
Formula
Note: Mine ventilation is statutory and life-safety territory: airflow quantities, gas limits and re-entry times must be set by the registered ventilation engineer/manager under your jurisdiction's mining regulations — this calculator is a planning and training aid.

About Dust & DPM — Drill Dust Capture Check
Dust & DPM — Drill Dust Capture Check computes the governing relationship C = escaped dust mass / air volume through heading live as you type. A single dry-drilled hole can shed more respirable silica than a week of wet drilling — capture efficiency is everything, and the difference between 95% and 99% is 5× the dose. This mass balance shows why drill-rig water systems get fixed TODAY, not at the next service. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Dust & DPM — Drill Dust Capture Check
- 1Enter your values — Holes per shift, Dust per dry hole, Capture/suppression efficiency, Heading airflow and more (sensible defaults are pre-filled).
- 2Read the live results: Mean added concentration.
- 3Check the "with your numbers" line to see C = escaped dust mass / air volume through heading substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Dust & DPM — Drill Dust Capture Check?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
