摘　　要：针对近期许多中—低变质程度的煤层出现CO长期超标,但煤层未曾出现自然发火的现象,进行了煤的变质程度对吸附CO影响的实验研究。通过测定煤的工业分析、元素分析、煤岩组分数据及其在30℃下对CO的等温吸附数据,利用Mathematic软件对实验数据进行了分析处理,得出在不同压力下,中-低变质程度的煤层对CO吸附量最大,为进一步研究煤层中一氧化碳赋存机理提供了依据,进而可减少不必要的自然发火预防措施的实施.In view of the phenomenon that the CO density is beyond the safe standard in many low and medium coal seams, spontaneous combustion does not happen the deterioration influence on CO absorption is studied. The proximate analysis, element analysis, macerals of coal and the CO absorption isotherm by coal samples at 30℃ are experimented. And making use of the mathematic software for analysis of the experimental data, it is found that the low-midum coal absorption is the highest under different pressures. It can provide the basis for studying the mechanism of CO absorption by coal, so as to decrease unnecessary prevention measure and incre.ase the economic benfit and ensure safe production in the coal mine.
