Abstract：For determination economical and reasonable spraying procedures, the whole-year filed campaign was carried out to investigate the water content change on the mine surface after spraying water. The moisture evaporative situation was decided by the factors, such as phase concentration difference, resistance and initial contact area between the gassolid interfaces after studying the moisture transfer characteristics occurring on the mine surface in the natural environment. Then, the experimental data was analyzed and a quantitative expression of the water content variable rate on the mine surface k with the atmospheric humidity, air velocity and ambient temperature was put forward. Consequently, it clearly defined the relationship between the moisture evaporative speed and each metrological factor.
