Способ оценки склонности каменного угля к самовозгоранию, включающий анализ влагосодержания отобранных проб угля, отличающийся тем, что определяют содержание влаги в мезопорах и микропорах, а для оценки склонности к самовозгоранию используют математическую формулу
Figure 00000001

где Wмезо - содержание влаги в мезопорах, %;
Wмикро - содержание влаги в микропорах, %;
X - показатель склонности угля к самовозгоранию,
причем при значениях X от 0,1 до 2,0 уголь относят к опасному по склонности к самовозгоранию, при значениях X от 2,0 до 2,5 - к малоопасному, а при X более 2,5 - к неопасному.A method for assessing the propensity of coal for spontaneous combustion, 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 propensity for spontaneous combustion
Figure 00000001

where W meso - the moisture content in the mesopores,%;
W micro - moisture content in micropores,%;
X is an indicator of the propensity of coal for spontaneous combustion,
moreover, with values of X from 0.1 to 2.0 coal is classified as dangerous in propensity to spontaneous combustion, with values of X from 2.0 to 2.5 - low hazard, and with X more than 2.5 - non-hazardous.
