| 摘 要： | One of the main aims of the coal industry is to improve conditions and increase the safety of the work. The questions of environment also need to be considered. In the complex of science-technological problems the focus is placed on how to reveal spontaneous combustion of coals and siltages. The results of spontaneous combustion of coals and siltages are bereavement of the minerals, promise for failures and accidents, and pollution of the environment. The decision of problem of the prevention is very hard, because the spontaneous combustion of coals is an unforeseeable and poorly studied process. The methods of preventing spontaneous combustion of coals must be established. In the first place, these investigations must start with the study of the structure of these coals. The aim of the present work is to determine the differences in the structure of coals with various susceptibilities to spontaneous combustion .Main methods of studying coals include ultimate and proximate analyses, petrographic analysis, analysis of ashes, X-ray （apparatus ＂Kristalloflex Siemens＂ using filtered cuprum radiation）, extraction （Dionex ASE 200）, gas chromatography-mass spectroscopy （GC-MS） Finnigan MAT GCQ. Proximate, ultimate and petrographic analyses revealed the distinction in the structure of coals with various susceptibilities to self-ignition.
