摘要
针对许多中、低变质程度的煤层出现CO长期超标,但未出现自然发火的现象,对24种不同变质程度的煤样进行了CO等温(30℃)吸附实验以及煤岩显微组分分析.研究表明:煤的镜质组含量、惰质组含量对CO吸附量影响较大,且对于中、低变质程度的煤,惰质组对煤吸附CO的影响大于镜质组对CO吸附的影响.利用Mathematic软件对实验数据进行分析处理,得出在不同压力下,惰质组含量与吸附量之间的数学模型.
In many low or medium rank coal seams, the carbon monoxide density was beyond the coal mine safety standard, but the spontaneous combustion didn＇ t appear. By examining the macerals of 24 kinds of coal samples in different rank and carbon monoxide absorption isotherm at 30 ℃, the research indicats that, for low or medium rank coal seams, carbon monoxide absorptive capacity of inertinite is stronger than that of the vitrinite. The mathematical models between the carbon monoxide absorption and the inertinite content were worked out under varying pressures.
