Coal Spontaneous Combustion Characteristics in Low-temperature Oxidation Environment and Anti Spontaneous Combustion Countermeasures for Railway Coal Transportation
Coal is a key material for railway transportation in Xinjiang,accounting for about 70%of the total shipment volume.However,due to the spontaneous combustion property of coal,there is still a fire hazard in the low-temperature oxidation environment of station storage and railway transportation,which poses a threat to the safety and production order of coal railway transportation.To explore the effect of a low-temperature oxidation environment on the spontaneous combustion characteristics of coal,this paper selected thermal coal from the Hami region in Xinjiang as a sample.The experimental methods were adopted to explain the self-ignition mechanism,characteristics,and ignition laws of coal during the low-temperature oxidation process from microscopic indicators.This paper analyzed the influencing factors of coal spontaneous combustion from a macro perspective through on-site research.Based on comprehensive analysis,measures to prevent coal spontaneous combustion were proposed,including improving rules and regulations,reviewing test reports,standardizing storage management,strengthening temperature monitoring,trialing technology for automatic temperature measurement,and carrying out flame retardant research.All these can provide a reference for ensuring the safety of railway"Xinjiang coal transportation".
