煤岩组分的物化性质对煤自燃的影响

影响煤自燃的因素很多,如煤化程度、煤的岩组成、煤的水分、黄铁矿含量、环境温度、煤堆积密度、煤炭粒度等。笔者主要研究煤岩组分的物化性质对煤自燃的影响。 There are many effects about coal spontaneous combustion such as degree of coalification,coal maceral,total moisture,pyrite content,ambient temperature,bulk density and size et al.The effect of physicochemical properties of coal maceral on coal spontaneous combustion has been studies in this paper
