[0005] In view of this, the purpose of the present invention is to provide a method for measuring the average wind speed of a roadway. Considering that the contour of the wind speed distribution of the roadway is a closed shape, it can be approximately regarded as a similar figure of the contour line of the roadway section. According to the law, the position of the roadway wind speed distribution contour is obtained, and the average wind speed of the roadway is measured at this position, which solves the problems of long measurement time, poor convenience and difficult measurement accuracy of the route method or fixed point method. It can adapt to the harsh environment of mines and improve It improves the efficiency and accuracy of measurement, and is easy to master and has a wider range of applications

Embodiment Construction
[0068] Such as figure 1 As shown, a kind of roadway average wind speed measurement method method provided by the present invention comprises steps:
[0069] S1: Measure the roadway waistline width or roadway axis height at the roadway wind measurement site;
[0070] S2: According to the width of the roadway waistline or the height of the roadway axis, obtain the position of the average wind speed line of the roadway section at the roadway wind measurement location;
[0071] S3: Measure the point wind speed at any point on the average wind speed line of the roadway section;
[0072] S4: Correct the point wind speed to obtain the average wind speed at the roadway wind measurement site.
[0073] Through the above method, according to the distribution law of wind turbulence velocity in the underground roadway, the contour line of wind speed distribution in the roadway is a closed shape, which can be approximately regarded as a similar figure to the contour line of the roadway se...

The invention provides a method for measuring an average wind speed of a tunnel. The method comprises the following steps: S1, measuring a tunnel waistline width or a tunnel axis height of a tunnel wind measurement location; S2, obtaining an average wind speed line position of the tunnel section of the tunnel wind measurement location according to the width of the tunnel waistline or the height ofthe tunnel axis; S3, measuring the point wind speed at any point on the average wind speed line of the tunnel section; and S4, correcting the wind speed of the point to obtain the average wind speedof the wind measurement location of the tunnel. According to the method for measuring the average wind speed of the tunnel, considering the distribution contour line of the tunnel wind speed is a closed shape and is similar to the contour line of the tunnel section, the position of the distribution contour line of the tunnel wind speed is obtained by analyzing the wind flow velocity rule of the tunnel section, the problems of long route method or fixed point measurement time, poor convenience and difficulty in measuring precision are solved by measuring the average wind speed of the roadway inthe position, the harsh environment of the mine can be adapted, the efficiency and accuracy of the measurement are improved, and the method can be easily mastered and more widely used.
Description
technical field [0001] The invention relates to the technical field of mine ventilation in mining engineering, in particular to a method for measuring the average wind speed of a roadway. Background technique [0002] With the normal development and production of the mine, the network of the mine roadway is constantly changing. In order to ensure the normal succession of underground production and the safe wind demand of the mine practitioners, it is necessary to update and adjust the mine ventilation network structure and the air volume of different wind locations in time. In the process of adjusting the mine ventilation network structure, by measuring the wind speed and air volume at different wind locations, we can further understand the distribution of wind speed and air volume in the mine's existing ventilation network structure, and provide a basis for the adjustment of the mine ventilation network structure. [0003] At this stage, mines in my country mainly use the l...
