Briquetting of coal fines is one of the best solutions for the disposal of substandard coal and coal fines. The coals of the Central region of Kazakhstan were selected as the object of this study. When stored for a long time, the coals of this region dry out and turn into coal fines that are not suitable for consumption. It is established that mechanical properties of composite briquettes depend on the charge composition and some technological parameters of briquetting, including: the material composition of the briquetted mixture, moisture mixture, compacting pressure, mode of heat treatment of the briquettes, the type and flow rate of the binder component. To optimize the combustion of the coal mass, the pyrotechnic component or polymer additives were added to mixture with the initial coal. The pyrotechnic component produces an incendiary layer, which contains as a combustible component (coal sludge, cardboard), a magnesium igniter and oxidizing agents in the form of ammonium nitrate and barium chromate. The greatest influence on the duration of burning of brown coal is exerted by oxygen-containing compounds (90 %). It was found in the laboratory research to obtain high-quality fuel briquettes, the following characteristics are necessary: coal size 0 - 2.5 mm; coal humidity 10 - 11 %; pressing pressure 150.0 MPa; processing temperature 230° C; heat treatment time of 180 min. The introduction of incendiary composition in the briquette does not lead to a significant reduction in the size and destruction of aggregates, while a significant part of the pyrotechnic composition is located on the surface of the coal in the form of particles with sizes from 145.8 to 368.6 nm, mainly in the form of "coagulants".
