• Effects of Obstructions, Sample Size and Sample Rate on Ultrasonic Anemometer Measurements Underground
  1/1/2012 - Peer reviewed journal articles
  This paper provides information about the effect of common obstructions in underground mining on air velocity readings.
• Sonic Anemometer Airflow Monitoring Technique for Use in Underground Mines
  6/1/2010 - Conference papers
  In this paper instrumentation and sampling strategies for accurate monitoring of airflow in an entry using two-axis and three-axis ultrasonic anemometers are evaluated.
• Using Ultrasonic Anemometers to Evaluate Face Ventilation Conditions
  2/1/2007 - Conference papers
  The fact that methane ignitions continue to occur at the mining face indicates that monitoring with machine-mounted methanometers does not always indicate the presence of high methane concentrations. Methane concentrations at the face change quickly du...
• Using Ultrasonic Anemometers to Evaluate Factors Affecting Face Ventilation Effectiveness
  1/1/2006 - Peer reviewed journal articles
  A test system was developed at NIOSH's ventilation test gallery to measure airflow using a three-axis ultrasonic anemometer. The gallery was used to simulate face airflow conditions in underground mines having a blowing curtain. Airflow data were used t...
• Evaluating Factors Affecting the Performance of Three-Axis Ultrasonic Anemometers
  5/1/2004 - Conference papers
  Provides guidelines for more effective use of the ultrasonic anemometer.
• Measurement of Airflow in a Simulated Underground Mine Environment Using an Ultrasonic Anemometer
  1/1/2004 - Peer reviewed journal articles
  Reports on a test system and computer program developed for using a three-axis ultrasonic anemometer to measure airflow in a simulated mine entry.
• Method Factors for Anemometer Measurement at Pipe Outlets
  1/1/1987 - Reports of Investigations
  Gob holes are routinely used by the mining industry to vent methane from gobs and to prevent it from entering the mine ventilation system. In some cases, flows from gob holes are measured by centering an anemometer on the end of a discharge pipe. These ...
