Abstract: The present invention provides a method for coal seam gas seepage displacement, seepage water locking and dust reduction. During the injection period, a pressure pump and pumping system are used to control the pressure and pumping flow rate, and a micro-nano bubble surface active liquid coupling medium is used for seepage displacement of coal seam gas, ensuring efficient discharge or extraction of coal seam gas. After the injection is completed, the micro-nano bubbles surface-active liquid coupling medium is stored in the coal seam, and the coal seam is subjected to seepage water locking and dust reduction. Through the seepage displacement, the seepage velocity of coal seam gas is increased. Through the seepage water locks, the desorption rate of coal seam gas is suppressed. Through the dust reduction, the wetting reversal of coal seams can be achieved, and the moisture content is increased, thereby reducing the generation of dust.
