Abstract
The results of experiments on DTGA of black coal from the Tavantolgoy deposit (Mongolia) are presented. It was discovered that intense voluminous expansion and at the same time agglomeration of coal material occur during thermal decomposition. This process is accompanied by the removal of gaseous, low melting and boiling components of coal. The effect of preliminary mechanical activation and its duration on the character of separation of thermolysis products was demonstrated. The suitability of coal without additional binding additives for briquetting was established.
