Federal regulations require that methane liberated at the face be diluted and removed to maintain methane gas concentrations below 1% in working places and intake air courses (30 CFR 75.323(b)(ii)). The delivery and distribution of intake air at the face is critical for effective face ventilation. Improved techniques for monitoring the movement of intake air to the face are needed. A test system was developed and a computer program was written for using a three-axis ultrasonic anemometer to measure airflow in a simulated mine entry. Results of tests conducted in the entry showed that the anemometer is a valuable tool for measuring mine airflow conditions near the face.
