为解决冬季北露天煤矿卡车道路洒水降尘与路面结冰的矛盾,首先分析确定润湿、保湿、凝并3种功能的组分单体为十二烷基苯磺酸钠(B)、甘油(N)、聚丙烯酰胺(R),确定复配防冻剂(F,质量分数为30%乙二醇+5%醋酸钾+10%甲酸钾);其次对B、N、R及F进行正交试验,测试渗透速率、抗蒸发性、黏度、冰点4个指标,确定防冻抑尘剂最佳配方B2N3R1F3及最佳体积稀释比1∶2。在现场试验路段喷洒防冻抑尘剂并持续6d检测路面含水率、全尘与呼尘浓度及粉尘粒径。现场试验结果表明:喷洒防冻抑尘剂后,路面平均含水率为12%;全尘与呼尘降尘效率为93%、91%;大粒径粉尘占比提高54.6%,且防冻抑尘剂具备胶结性能与返潮性能。研究成果可为解决露天煤矿卡车道路既抑尘又防冻的问题提供理论依据。

In order to solve the contradiction between sprinkling water to reduce dust and road surface icing for truck road in North Surface Coal Mine in winter, firstly, the three functional components of wetting, moisturizing and coagulation were determined by analysis as sodium dodecyl benzene sulfonate ( B), glycerol ( N), polyacrylamide ( R), and the compound antifreeze ( F,30% glycol + 5% potassium acetate + 10% potassium formate by mass fraction) was determined. Secondly,the orthogonal test was carried out with B,N,R and F. The four indicators of permeation rate,evaporation resistance,viscosity and freezing point were tested to determine the best formula of antifreeze dust inhibitor B N R F and its optimal volume dilution ratio of 1 ∶2. The anti-freeze dust suppressant was sprayed on the field test road section. Continuously test the water content of road surface,total dust,exhaled dust,and dust particle size of the road surface for days. The field test results show that the average water content of the road surface is 12% after spraying anti-freeze dust suppressant. The dustfall efficiency of total dust and breath dust are 93% and 91%. The proportion of large particle size dust increased by 54. 6%,indicating that the anti-freeze dust suppressant have cementation performance and moisture regain performance. The research results provide theoretical basis for effectively solving the problem of antifreeze and dust suppression on trucks road in coal mine.
