| 摘 要： | 为提高煤矿安全保障能力和职业健康水平,降低煤尘尘肺病等职业病危害,快速且准确判断不同抑尘剂的抑尘效果,研究煤尘抑制剂的固化层厚度、抗风蚀特性、单轴抗压强度(UCS)、贯穿阻力等常用性能评价指标,通过各评价指标的试验方法、不同影响因素下性能差异分析各评价指标的准确性。分析结果表明:使用固化层厚度、抗风蚀特性、UCS评价指标来判断煤尘抑制效果较差,贯穿阻力能较好地判断煤尘的抑制效果。

| Abstract: | 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. |

| Keywords: | dust suppressant evaluation indexes wind erosion resistance uniaxial compressive strength(UCS) penetration resistance thickness of solidified layer |
