The pore capacity is becoming smaller with increasingthe vitrinite content. 2. Micro-porosity is dominated in the total pore capacity, which takes more than50%. There is not relationship among pore capacity and specific surface with otherfactors such as Maceral and R0, which shows that the distribution and shapes of poreare not influenced by the composition of the coal. 3. The pore is opened for the coal of Ordos Basin, the order is from durain to clarainthen samples to vitrain. Others are belong to half-opened and thin throat. 4. The adsorption content of gas is increasing with the higher pressure, and the freegas content is decreasing;The adsorption content of gas is decreasing with thehigher temp, and the free gas content is increasing;The adsorption content of gas isincreasing with higher vitrinite content for the kennel coal when temp.
总空隙主要由小孔孔容构成,小孔孔容占了50%以上;镜质组含量和惰性组含量等物质以及镜煤反射率均与孔容、比表面未表现出明显的相关性,说明孔隙分布特征不受物质组成的影响 3、鄂尔多斯地区的空隙呈现开放状态为主,空隙开放的次序为暗煤-亮煤-煤样-镜煤,其他盆地则为半封闭和细瓶颈空隙 4、随压力增加,煤对气体的吸附量增加,煤中所含游离气的量随之减小;随温度增加,煤对气体的吸附量减小,而煤中所含游离气的量随之增加;在相同的温压条件下,同是长焰煤的样品,吸附量在孔容中所占的比例随镜质组含量增加而增加。

Seven coals from Shenfu, Huangling, Huating, Yaojie, Lingwu, Datong and Urumuqi coal districts were selected as samples to study in this project. At first, petrographic characteristics, proximete and ultimate were done upon the coals.Lithotypes as vitrain, fusain, clarain and durain were separated.
本项目选择我国西北地区的神府矿区、黄陵矿区、华亭矿区、窑街矿区、灵武矿区、大通矿区、乌鲁木齐矿区的七种煤,首先进行了煤岩、煤质研究,得出这些煤的惰质组含量普遍较高。

But, fusain is high in density and in HGI. It is usually concentrated in the coals of heavier and finer parts. Less oxygen functional groups exists in vitrain even if the total oxygen is high. However, more oxygen functional groups is found in fusain though total oxygen is low.
指出,镜煤的密度较低、HGI值较小、易富集于密度较氢的粗粒径煤中,尽管其总氧含量较高、但是含氧官能团的数量相对较低,丝炭的密度较大、HGI值较高、易富集于较重的细粒径煤中,其总氧含量尽管较低、但是含氧官能团的数量较高。

Characteristics of preparation and separation, and some other technological features were further studied. It concluded that vitrain is low in density and in HGI. It is rich in lighter and corser parts of the coals.
然后,进行了各煤岩组分的工业分析、元素分析、密度测定、HGI测定、表面基团测定、表面电位测定、润湿热分析、比表面积和孔经测定,进而深入研究了其分选性质和其他工艺性质。

Research on Coal-forming Environment and Sequence Stratigraphy in Coal Measures Strata;2. The results show:1, there were the differences between the characteristics of the coalification between the Taiyuan Formation vitrain and the Shanxi Formation vitrain which were formed in differencial coal-forming environment s, and the differ.
结果表明:在高煤级煤早期阶段,形成于不同成煤环境的太原组煤与山西组煤的煤化特征仍有差异,在第三次煤化作用跃变之后这种差异逐渐缩小消失;高煤级煤分别以第三次和第四次煤化作用跃变为界,呈现出阶段性演化的特征,每阶段的演化机理有所不同;第三次煤化作用跃变中大分子结构的演化以芳构化作用主为,第四次煤化作用跃变则以强烈的环缩合作用占优势。
