Способ оценки склонности каменного угля к окислению, включающий анализ влагосодержания отобранных проб угля, отличающийся тем, что определяют содержание влаги в мезопорах и микропорах, а для оценки склонности к окислению используют математическую формулуA method for assessing the tendency of coal to oxidize, including an analysis of the moisture content of the selected coal samples, characterized in that the moisture content in the mesopores and micropores is determined, and a mathematical formula is used to assess the susceptibility to oxidation

 где Wмво - содержание влаги в мезопорах, %;where W MVO is the moisture content in the mesopores,%; Wмикр о - содержание влаги в микропорах, %;W micr about - moisture content in micropores,%; F - показатель склонности угля к окислению, причем при значениях F от 0,1 до 2,0 уголь относят к опасному по самовозгоранию, при значениях F от 2,0 до 2,5 - к малоопасному, а при F более 2,5 - к несклонному к окислению.F is an indicator of the tendency of coal to oxidize, and with values of F from 0.1 to 2.0 coal is classified as dangerous for spontaneous combustion, with values of F from 2.0 to 2.5 - low hazard, and with F more than 2.5 - to averse to oxidation.
