As coal mining continues to progress deeper levels, the temperature of and rock rise, causing spontaneous combustion disasters become increasingly prominent. This paper studies characteristics in a high environment before after seam mining. The results were as follows: 1) Before mining, under action constant ground temperature, deep continuously slowly released heat, higher was, more heat was released. 2) During air entered, samples initially maintained continuous slow release. With entry...
Currently, research on coal spontaneous combustion (CSC) mostly focuses its macroscopic behavioral characteristics. However, there is still a significant gap in exploring the role, pathways, and mechanisms of micro functional groups process under complex conditions. Therefore, this paper utilizes VERTEX 70 V in-situ Fourier Transform Infrared (FTIR) Spectroscopy to investigate impact air leakage (AL) disturbance increase temperature affects microscopic within coal, further revealing...
As the depth of coal mining continues to increase, weight overlying strata and ground stress on residual in goaves also increase. At same time, temperature rocks rise, high environment heading faces becomes more severe. a result, oxidation spontaneous combustion disasters become prominent. In this work, an anaerobic heating experiment under thermal-mechanical coupling effect was performed. The effects thermal stability were studied by analyzing parameters such as heat flow peak temperature,...
To study the effect of air leakage (AL) and water immersion in goaf on spontaneous combustion coal, a C600 microcalorimeter was used to analyze oxidation heat release characteristics raw coal (RC) (WIC) under different AL conditions at stages. The experimental results show that can have effects various stages combustion. is negatively correlated with intensity (HRI) initial stage positively HRI increasing degree oxidation. For RC, sufficient, absolute oxygen content high, flow (Q) curve...
