The spontaneous combustion latency is the initial stage of coal spontaneous combustion
and provides the primitive thermal resource for it. Study on this process is of great …

Mine fire has always been a serious disaster in coal industry; many academic achievements
have poured out in the past two decades for solving this problem. In this study, visual …

Petcoke is a byproduct of heavy crude oil refining at an enormous scale, and insights into
the physicochemical properties, thermal degradation behavior, decomposition kinetics, and …

The influence of prepyrolysis temperatures on the spontaneous combustion of wetting coal
remains unclear from a macroscopic perspective. To this end, a low-ash and high-volatile …

Igneous intrusion in coal measures is a common phenomenon in many coalfields
worldwide. This process forms various degrees of metamorphic coal due to the complex …

Spontaneous combustion of coal occurs when exposure to ventilation air initiates a gradual
oxidation process, generating heat. In restricted air supply conditions, the temperature of the …
