The characterization of free radical reaction in coal low-temperature oxidation with different oxygen concentration
Buzhuang Zhou,Shengqiang Yang,Chaojie Wang,Xincheng Hu,Wanxin Song,Jiawen Cai,Qin Xu,Naiwen Sang +7 more
TL;DR: In this paper, the oxygen concentration of airflow was dynamically adjusted to simulate the natural oxidation of coal at different depths in goaf with the aid of a self-built simulation experiment system of low-temperature coal oxidation.
Journal ArticleDOI
Forecast of coal spontaneous combustion based on the variations of functional groups and microcrystalline structure during low-temperature oxidation
TL;DR: In this article, a low-temperature oxidation of coals with different metamorphic degrees was analyzed based on the gas chromatographic analysis of gas products and the FTIR determination of oxidized coal samples.
Journal ArticleDOI
Low-temperature oxidation of free radicals and functional groups in coal during the extraction of coalbed methane
TL;DR: In this paper, the low-temperature oxidation of coal in an air flow containing coalbed methane (CBM) was analyzed based on the oxidation reaction of free radicals and functional groups.
Journal ArticleDOI
Prediction of gas and coal spontaneous combustion coexisting disaster through the chaotic characteristic analysis of gas indexes in goaf gas extraction
TL;DR: Wang et al. as mentioned in this paper took the gas samples from gas drainage pipeline in the goaf of 1203 working face of Hongyang No. 2 Coal Mine, and then analyzed the chaotic characteristics of coal gas indexes from gas draining pipeline by using the R/S analysis method.
Journal ArticleDOI
Micro-structure of crushed coal with different metamorphic degrees and its low-temperature oxidation
TL;DR: In this article, the free radicals and functional groups of coal with different ranks in the crushing process were analyzed based on electron paramagnetic resonance (EPR) and Fourier transform infrared (FTIR) spectrometry.
