Spray dust reduction technology is one of the most widely used dust reduction technologies in underground mine, but there are some problems such as poor spray atomization effect and low dust capture efficiency. In order to guide the efficient application of downhole spray dust reduction technology, this study takes ultrasonic atomization dust reduction technology as the research object, and uses laboratory experiments to study the influence of gas-water pressure on ultrasonic atomization parameters. The results show that the air pressure has a significant effect on the ultrasonic spray range, atomization angle and droplet size. With the increase of air pressure, the ultrasonic spray range increases logarithmically, the atomization angle increases nearly linearly, and the droplet size decreases significantly. The water pressure has no significant effect on the ultrasonic spray range, but has a significant effect on the atomization angle. The larger the water pressure, the smaller the spray atomization angle.
