The influence of the mine dust mineral composition on the characteristics of thermal destruction processes

Abstract

The article describes the results of comprehensive laboratory tests of mine dust samples taken from active mine faces in the Kuznetsk coal basin (Kemerovo region, Russia). The purpose of the experiments is to study the characteristics of thermal destruction processes in mine dust depending on its mineral composition. Based on the results of electron microscopy, the mineral composition of the dust samples under study was determined, and the quantitative relationships of the mineral phases composing the sample were assessed. Using thermogravimetric analysis the lower limits of thermal destruction intervals were established for samples of mine dust with different compositions and percentages of mineral inclusions. The practical significance of the results obtained is substantiated.
