Single-point Method of Mine Roadway Average Wind Speed Based on CFD Numerical Simulation

Making use of numerical simulation analysis about wind velocity field on 111811 working face in Panjiang Jinjia Coal Mine, this paper draws a conclusion that the wind velocity of a spot in section has a linear relation with average wind speed of this section. Dealing with the data from numerical simulation with mathematical software Matlab, linear function is simulated. According to the function fitting, average wind speed of section could be simulated by measuring wind velocity of a spot.
