6/1/2010 - Conference papersIn this paper instrumentation and sampling strategies for accurate monitoring of airflow in an entry using two-axis and three-axis ultrasonic anemometers are evaluated.
-
1/1/2010 - Peer reviewed journal articlesThis paper discusses some ways to find extra usable air when there is no extra ventilation capacity.
-
2/1/2009 - Conference papersThis paper discusses the current ventilation practices regarding the use of belt air during gateroad development and longwall panel extraction.
