摘　　要：针对露天矿道路抑尘效率不足、抑尘水分流失迅速的问题,选用3种生物基质单体抑尘材料,利用正交实验方法进行了复配研究。通过考查复配剂保水性能、溶液黏度等指标,优选出抑尘效果最佳的复合比例及适宜的使用浓度区间。实验结果表明,抑尘原料A、B、C的最佳复配比例为6∶4∶3,适宜的使用浓度为0.1%~0.2%。当溶液浓度达0.1%后,复配剂黏度迅速增加,3 d后该复配剂保水率仍可达37.0%以上。工业性试验表明,浓度为0.1%的抑尘剂,总粉尘与呼尘的抑制效率较喷洒清水时分别增加34.0%与35.5%,该复配抑尘剂具有良好的保水、黏结、固尘性能,可实现露天矿道路的高效降尘。In order to solve the problem of insufficient dust removal efficiency and rapid loss of dust suppression moisture in open-pit road,orthogonal experiment was used to study the compounding study by selecting three biological matrix monomer dust suppression materials.By examining the water retention performance and solution viscosity of the composite agent,the optimal composite ratio and suitable concentration range for dust suppression were selected.The results showed that the optimum compounding ratio of dust suppression material A,B and C was 6∶4∶3 and the suitable concentration was 0.1%~0.2%.When the solution concentration reached 0.1%,the viscosity of the compounding agent increased rapidly,and the water retention rate of the compounding agent can still reach over 37.0%after three days.The industrial experiment showed that when the concentration of dust suppressant was 0.1%,the dust suppression efficiency of total dust and respirable dust increased by 34.0%and 35.5%,respectively,compared with that when the water was sprayed.The compounding dust suppressant has good water retention,adhesion and dust fixation performance,and can effectively improve the dust suppression efficiency on open-pit mine roads.
