Abstract

The physicochemical properties of coal dust from fine filters in the degassing system of a Kuznetsk Basin mine are studied. The dust sample is investigated by atomic-emission spectroscopy, IR spectroscopy, dynamic light scattering, and thermal analysis. The dust undergoes technical analysis and granulometric analysis; the textural characteristics of its pore structure are analyzed by adsorption. Finally the change in chemical composition of the mineral components in the dust is expressed as a function of the particle size.

用动态光散射法测定煤尘的成分和粒度

摘要

研究了库兹涅茨克盆地矿山脱气系统中细滤器煤尘的理化性质。通过原子发射光谱、红外光谱、动态光散射和热分析对粉尘样品进行研究。粉尘经过技术分析和粒度分析；通过吸附分析其孔结构的织构特征。最后，粉尘中矿物成分的化学成分变化表示为粒度的函数。
