N2  - In order to improve safety capability and occupational health level of coal mines, to reduce occupational hazards such as pneumoconiosis, and quickly and accurately assess suppression performance of different dust suppressants, commonly used evaluation indexes, such as solidified layer thickness, wind erosion resistance, UCS and penetration resistance of such suppressants, were studied, and their accuracy was analyzed based on test methods of each index and their performance difference under various influencing factors. The analysis results show that evaluation indexes like solidified layer thickness, wind erosion resistance and UCS exhibit poor performance in assessing dust suppression effect, while penetration resistance proves to be better for that. © 2022, Editorial Department of China Safety Science Journal.
