煤自燃倾向性鉴定实验方法探讨

Discussion on experimental method of coal spontaneous combustion tendency identification

目前国内煤炭自燃分类等级的鉴定基础研究还较为片面,现有的煤自燃倾向性色谱吸氧法反映出煤表面对氧的物理吸附特性,煤自燃倾向性氧化动力学测定法反映煤氧化的内在动力学特性。为此,该论文对AQ/T 1068-2008《煤自燃倾向性的氧化动力学测定方法》[1]和GB/T 20104-2006《煤自燃倾向性色谱吸氧鉴定法》[2]进行了研究分析。

At present domestic coal spontaneous combustion classification identification of the basic research is still relatively one-sided, existing oxygen coal self-ignition orientation chromatographic method reflects the physical adsorption characteristics of coal surface to oxygen, coal spontaneous combustion propensity to oxidation kinetics measurement reflects the inherent dynamic characteristics of coal oxidation. To this end, the paper to AQ/T 1068- 2008 the self-ignition orientation of coal oxidation kinetics determination method and GB/T 20104-2006 ／＂oxygen coal self-ignition orientation chromatography assay method／＂ are analyzed.
