Analysis and optimization of multi-parameter fusion criteria for predicting spontaneous combustion of coal in goafs
摘要
Abstract
This paper intends to improve the prediction and early warning capability for spontaneous combustion fires in goafs.By taking the coal samples in Dongrong No.2 Coal Mine as the research ob-ject,the study conducts the temperature-programmed experiments to determine the characteristic gas indi-cators at different temperature stages.The results indicate that the critical temperature of spontaneous combustion of the tested coal sample is 70-80℃,the dry cracking temperature is 110-120℃,and the crossing point temperature is 120℃.The CO volume fraction can be used as the primary indicator for predicting the spontaneous combustion of the coal sample.The detection of H2 is selected as an auxiliary indicator for coal temperatures reaching 70℃;and the Graham fire coefficient R2,as well as the inflec-tion points of CO and CO2 generation rates,serve as auxiliary indicators for coal temperatures reaching 110℃.The findings provide a certain reference for the early prediction and warning of spontaneous com-bustion in the goaf of Dongrong No.2 Mine.关键词
