Abstract
The Bureau of Mines has refined the original spray-fan system (water sprays that move and direct air) into a simpler and more effective improved spray fan. The system has concentrated sprays at the mine hinge point and increased front spray power and angle to improve the face ventilation of a full-scale laboratory model. Tracer gas testing in the model showed a 40-pct improvement in face ventilation over the original spray-fan system.
