摘要： 针对露天采场路面扬尘特点及机理，研制出一种吸湿型路面抑尘剂.基于正交试验，以失水率为评价指标，对抑尘剂各组分进行优化，并在实验室条件下对最优配方进行吸湿性、抗风吹等性能测试.结果表明，实验室研制的配方在25d内最低含水率达到8.18%，具有很好的防风抑尘性能.将该抑尘剂配方进行工业试验，结果表明，该抑尘剂的有效抑尘时间为10d，与传统洒水方法相比，抑尘费用降低了30.71%，节水效率达到94.67%.

Abstract: Based on the characteristics and mechanisms of open pit road dust， one hygroscopic road dust-depressor was developed. The components of the dust-depressor agent were optimized by taking water loss rate as the evaluation index， which is based on the orthogonal test. The hygroscopicity， wind resistance and other properties of the optimal formula were tested in a lab environment. The results showed that the moisture contents of the optimal formula were all above 8.18% within 25 days， indicating that the optimal formula had a very good windbreak performance. Taking the optimal formula to industrial testing， it was found that the effective time of dust suppression is 10 days. Compared with the traditional water spraying， it could reduce the cost for dust suppression by 30.71% and increase the water-saving efficiency up to 94.67%.

Key words: road dust, hygroscopic road dust-depressor, water loss rate, instantaneous dust concentration, dust diameter distribution
