❓ Can the setback distance of a mine ventilation duct be increased without losing efficiency?
New research has proven: even with a 21-meter setback from the working face, the air jet maintains its effectiveness, fully ventilating the dead-end drift.
🔹 Key findings:
✔️ Experiments conducted in an actual 29.2 m² cross-section drift with five setback variants (10-21 m)
✔️ 21.75 m/s jet velocity ensured proper ventilation even at maximum distance
✔️ Results verified through computer modeling
✔️ Derived equation correlates face velocity with drift geometry
🔹 Why it matters:
The discovery allows safely increasing duct setback to 20m for large cross-section drifts, simplifying mining operations.
