摘要
为提高抑尘剂的降尘效果,探究露天矿爆堆粉尘润湿性及其影响因素。以哈尔乌素露天煤矿不同爆破台阶爆堆产生的煤尘及岩尘为研究对象,采用室内试验和数据统计分析等方法,分析露天矿爆破粉尘颗粒理化特征,并在此基础上讨论其理化特征与润湿性关系,采用SPSS软件进行回归分析,建立回归模型,最终由回归方程得知影响露天煤矿爆堆粉尘润湿性的主要因素。结果表明:影响煤尘润湿的显著因素是固定碳含量和粉尘粒径D_(50);影响岩尘润湿的显著因素是D_(50)。
In order to enhance the dust suppression effectiveness of dust suppressants,the wettability of dust from blast piles in open-pit mines and their influencing factors were investigated.The coal dust and rock dust generated from different blasting stages at the Ha′erwusu open-pit coal mine were taken as research objects.Various methods,including indoor experiments and statistical data analysis,were employed to analyze the physicochemical characteristics of explosive dust particles from open-pit coal mines.Based on this analysis,the relationship between physicochemical characteristics and wettability was discussed.Regression analysis using SPSS software was conducted to establish a regression model.The final regression equation revealed the primary factors influencing the wettability of dust from blast piles in open-pit coal mines.The results indicate that the significant factors influencing the wettability of coal dust are fixed carbon content and D_(50).The significant factor affecting the wettability of rock dust is D_(50).
