Overview

Observational study reveals optimal sprinkler design enhances dust removal in tunnel construction, suggesting improved safety measures.

Key Points

  • This research investigates how different sprinkler layouts affect dust removal efficiency during tunnel construction.
  • Integrated numerical simulation and experimental validation
  • Analyzed spray angle and location variations
  • Examined dynamic characteristics of water mist and dust spatial evolution
  • Highest spray concentration occurs 15-25 m from the tunnel face
  • Dust removal efficiency reaches up to 86.7% with optimal angles
  • PM2.5 concentration reduces by 73.84% post-spraying
