The objective of this work is to determine if a three-axis ultrasonic anemometer could be used to evaluate airflow movement in a test facility where underground mining conditions were simulated. The paper describes the development and use of a protocol for collecting and analyzing data obtained with the anemometer.
Secondly, we used the PSO to optimize the parameters of the KELM. The evaluation indexes of the PSO-KELM on the test set are better than other regression models. Finally, the accuracy of the PSO-KELM was verified by experimental data obtained by the ultrasonic anemometer in the wind tunnel.

Mechanical anemometers are an instrument used to determine the volume of air entering or exiting mine workings. They were invented by Benjamin Biram, house steward to the Earl Fitzwilliam, owner of numerous collieries in South Yorkshire, England, in 1844. The formula used most often in mine ventilation using an anemometer was q=av, in which q ...
