dc.description.abstractThe phenomenon of coal modification at oil ag- glomeration has been studied, specifically, changing of its structure and physical-chemical properties of surface. It was established:- agglomeration process of coal with size 0-1(3)mm is accompaning by direct adhesive contact of “coal-oil” on 75-80 % from external surface of coal. The high power chemical bonds are formed together with physical bondes in the interphase zone. This modification lead to the increasing hydropho-bity of coal surface and the contrastance of mozaic liophylic-liophobic picture. - internal surface of coal is hydrophobized by diffusing oil agent into pores and fissures. Infiltration phenomenon intensifies this process since light fractions of a binder penetrate into micropores of coal substance. - the changings in supermolecular structure of coal organic mass(COM) have been revealed in oil agglomeration process. The experience carried out on low rank salty coals of Western Donbas.en
