| 摘 要： | 基于和顺区块22个贫煤煤样平衡水等温吸附成果,分析了和顺贫煤的吸附特征,探讨了影响贫煤吸附的因素.研究表明贫煤总体吸附性较强,兰氏体积较高、兰氏压力较低,吸附能力与煤化程度、孔隙率、比孔容、比表面积正相关,与水分含量、灰分含量负相关,显微煤岩组分的影响较微弱.

| Abstract: | Based on the results of isothermal adsorption experiments on 22 meagre coal samples under equilibrium moistures in the Heshun Area,the adsorption characteristics of meagre coal was analyzed,and influence factors of its adsorption property was investigated.The research shows that the meagre coal have strong capacity to adsorb CBM in general,with higher Langmuir volume and lower langmuir pressure.The adsorption capacity of the coal has a normal correlation to the degree of coal evolution,the porosity,the spec... |
