Overview

Randomized trial investigates airflow velocity distribution in irregular mine roadways, indicating the importance for ventilation safety.

Key Points

  • This study aims to measure and analyze airflow velocity distribution in irregular mine roadways for improved ventilation management.
  • Numerical simulation using Fluent software to create 3D models of roadway types and dimensions.
  • Field testing conducted in Taoyuan Coal Mine with a hot-wire anemometer for point velocity measurements.
  • Nonlinear fitting was applied to relate point wind speed to distance from the roadway wall.
  • Relative error between numerical simulation and field measurement is within 5%.
  • Average wind speed line located 0.11 times the roadway width/height from walls in regular cross-sections.
  • Velocity distribution patterns reveal complex behavior in turbulent regions, ensuring accurate sensor placement.
