Abstract
There is a certain difference between the wind speed measured by the wind speed sensor in the underground coal mine and the manually measured wind speed.In order to explore the relationship between the wind speed sensor and the manually measured wind speed,the wind speed was measured in two different ways on site in the typical tunnels of the 30107 working face,namely the transportation channel and the south wing auxiliary transportation roadway.It was found that the manually observed values were generally higher than the measured values of the wind speed sensor.The average manually measured wind speed value in the 30107 transportation roadway was about 0.2 m/s higher than the sensor measurement value,and the height of the south wing auxiliary transportation roadway was about 0.3 m/s higher.By using the principle of least squares,the variation law between two wind measurement methods was obtained through fitting and comparative analysis.This provides technical support for guiding the rational use of wind speed sensor data in practical work,accurately grasping the ventilation parameters of each roadway,reducing the complexity of manual wind measurement work,and further improving mine ventilation monitoring management and technology.关键词
