摘要：Coal seam waterflooding hydraulic wetting has been widely used in coal mines, and plays an increasingly important role in coal and gas outburst prevention, dust prevention, and rock burst prevention. In order to explore the mechanism of coal and gas outburst prevention and control by hydraulic wetting, this paper analyses the three stages of hydraulic wetting through Gibbs function: wetting, soaking and spreading; explains the solution of the three stages through Young's equation, and finally discusses the release and stress of coal gas potential caused by water movement in coal. The centralized influence provides a theoretical basis for the application of coal and gas outburst prevention and control technology in mines.
