Abstract

The properties and efficiency of a solid–liquid suspension based on ground blast furnace slag, which is used to deactivate the processes of oxidation and spontaneous combustion of coals, have been studied. It has been established that sequential impregnation of coal with water-soluble and thickened components of the slag suspension promotes uniform passivation and a decrease in the oxidative activity of the external contacting surface. The results obtained justify the effectiveness of using slag waste as a constituent of technological suspensions for the insulation plugging of a coal seam.

高炉矿渣悬浮液处理煤炭对表面物化性能变化的影响

本文研究了一种用于煤的氧化和自燃过程灭活的基于高炉渣的固液悬浮液的性能和效率。研究表明，用矿渣悬浮液的水溶性组分和增稠组分依次浸渍煤，促进了煤的均匀钝化，降低了煤的外接触面氧化活性。研究结果证明了利用矿渣渣作为工艺悬浮液对煤层保温封堵的有效性。

期刊介绍： The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
