These mineral resources are important basic raw materials or industrial raw materials in industry. For example, coal can be used in power generation, smelting and other fields.

[0003] In order to understand the internal ventilation and wind flow distribution of mines and ensure the safe production of mines, most people currently use the fixed-point wind measurement method, that is, select a measuring point in the mine, place the anemometer at the measuring point for a certain period of time, and calculate the average wind speed at the point based on the anemometer reading and the measurement time.

[0004] However, when measuring wind speed using the fixed-point wind measurement method, the anemometer only performs measurements at a fixed position in the mine. The measurement data is not sufficient to reflect the wind field conditions in a wide area, making it difficult to subsequently understand the overall distribution of wind force, and has certain limitations.
