摘　　要：露天矿运输过程中,车速、路面粉尘负荷、粉尘含水率与扬尘浓度有密切的关系.通过对它们设计正交试验和多元回归统计分析,得到运输扬尘质量浓度的计量模型,该模型具有99%的显著性和拟合性.经回归系数显著性检验,自变量对因变量的影响均极为显著,其显著性大小依次为:车速、粉尘含水率和路面粉尘负荷.最后采用实测值与模型计算值的计算机拟合,对模型进行验证.结果表明,该模型具有较高的可信度.Vehicle velocity, road dust load, and dust moisture have close relationships with dust mass concentration. Based on orthogonal experiment and multiple regression statistical analysis, a calculation model of dust mass concentration in traffic was established, with a significance of 99 % and a better goodness of fit. The results of significance test of regression coefficients show that the effects of the independent variables on the dependent variable are very significant, with the order of vehicle velocity, road dust load and dust moisture. The agreement of the computed results with test data indicates that the model has high reliability.
