Coalification is essentially a process of the change of physicochemical structure and physicochemical properties under the influence of temperature, pressure and time.

煤化作用实质上是在温度压力及时间等因素的作用下，煤的物理化学结构的变化及由此导致的煤的物理化学性质的变化，因此，了解煤化作用过程中物理化学结构的变化是深入理解煤化作用机理及过程的关键。

Because of the complexity of the coalification process and the diversity of the coal-level indicators ,it was induced that resulting in different coalification stages the coal-level indicators were significantly different and coal-division was rather difficult.

煤化过程的复杂性和煤级指标的多元性，导致不同煤化阶段中的各煤级指标显著不同，煤级划分比较困难。

The results indicate that the sedimentation behavior of coal particles of CWS belongs to differential sedimentation and there is a conglobation between coal particles in CWS preparation. Stability of CWS prepared with lignin series dispersants is better than that prepared with naphthalene series, and the height and mean sedimentation rate of clarifying zone is about 68% of that of FDN when the dosage of additives is 1.0%.

结果表明，水煤浆中煤粒沉降行为为差异沉降，在水煤浆制备过程中，煤颗粒之间会发生团聚，掺1.0％GCL3S的水煤浆清液区高度及平均沉降速率仅为掺FDN的68％，木质素系分散剂制备的水煤浆稳定性能优于萘系。

This model indicates that the sulfur isotopes, whose values tend to be negative fractionate to a large scale because of the reductive process of dissimilating bacteria of sulfate.

根据内蒙古乌达矿区高硫煤9煤层（有机硫同位素值 d 34 S=－12.3‰~5.8‰，黄铁矿硫同位素值 d 34 S=－18.7‰~1.1‰）和低硫煤13煤层（有机硫同位素值 d 34 S 为8.9‰~ 11.5‰，黄铁矿硫同位素值 d 34 S 为8.3‰~ 9.7‰）剖面上有机硫和黄铁矿硫同位素的组成，结合煤岩学特征的综合分析以及黄铁矿化菌落和蓝藻胶壳的发现，提出了高硫煤中硫的演化模式，认为高硫煤中硫的同位素由于硫酸盐的异化细菌还原作用导致硫同位素大规模分馏，使之趋于负值。

In this paper, Petrographical coal blending and predicing coke quality were done using 15 kinds of normal coal, by 40Kg coke oven and using microphotometer and polarized light microscope to check the quality of the coke, on the basis of investigation of quality, stability and price of about 30 kinds of coking coal recently used by ANGANG GROUP.

本文在对鞍钢近年使用的约30种炼焦煤的质量、稳定性及价格充分调研的基础上，选择了15种常用煤为实验煤种，以40Kg实验焦炉为炼焦手段，以显微光度仪和偏光显微镜为煤岩检测工具，开展了煤岩配煤与预测焦炭质量的研究工作。

The application of coal petrography technology in coking coal blending makes the blending method more effective and the prediction of coke quality possible, which creates condition for the qualitative experiential coal blending being developed into a scientific quantitative one.

煤岩学在炼焦配煤技术上的应用，使炼焦配煤手段更有效，使焦炭质量预测在生产上应用成为可能，为定性的经验配煤技术跃变到定量的科学配煤技术创造了条件。

Preliminary study of coal chemistry and coal petrography about the raw material used to prepare for HA—type binders indicated that the content of free humic acid in the coal is excellently linear with the binder properties.

本文对制备HA型粘结剂的原料进行了煤化学、煤岩学的初步研究，煤化学的研究表明，原料煤中游离腐植酸的含量与煤对应粘结剂的性能呈正相关性且线性关系较好。

It is quite different in the powder properties between Indonesian coal A and Indonesian coal B based on the analysis of Fourier transform infrared spectroscopy and scanning electronic microscope so as to solve the problem of powder agglomeration during the operation of medium-speed coal pulverizer.

为了解决中速磨煤机磨制印尼煤时的煤粉团聚问题，利用傅立叶红外光谱和扫描电镜对印尼A煤和B煤进行了分析，发现这两种煤的粉体特性相差很大，印尼A煤含有容易团聚的官能团。

The results show that: the functional groups in coal are the function of coal rank , and the yields of CO 2, H 2O and CO are related to the content of carboxyl, hydroxyl and other oxygen containing groups such as ether groups in coal, and Tar and CH 4 are related to the aliphatic CH, the char yields to the aromatic CH.

借助化学分析和FTIR光谱分析对我国煤化程度不同的18 种煤中官能团的研究表明：煤中官能团含量与煤化程度有关；煤中羧基、羟基及醚键等其他含氧官能团的含量与热解生成物CO2、H2O 和CO 的产率有关，脂肪—CH 的含量与甲烷和焦油的产率相关联，芳香—CH 的含量与热解半焦产率有关。
