摘要：
The infusion increase mechanism of power ultrasound on coal seam water infusion and its prospect of application are introduced. The research results show that: The physical and mechanical properties of coal changed, coal bulk modulus and compressive strength decreases and porosity and permeability of coal can be improved due to the power ultrasound, so the effect of coal seam water infusion preventing coal and gas outburst can be strengthen. The main mechanism of power ultrasound on coal and water are mechanical and cavitations function. The technology of power ultrasound on the coal seam water infusion has a good application prospect.
