1) Ingredient indexes
煤岩指标
2) coal and rock crushing index
煤岩破碎性指标
3) the coal-level indicators
煤级指标
1.
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。
4) Parameters of coal properties
煤质指标
1.
Some parameters of coal properties which are not a linear combination of the individual index in weight of blending coal, such as Hardgrove grindability index (HGI), screen analysis, ash fusibility, ect.
从煤在不同类型锅炉的燃烧方式出发，讨论了煤质特性对燃烧工况及对环境的影响，以及一些非加和性煤质指标，如可磨性、粒度组成、煤炭熔融性等对动力配煤的影响，进而提出选定动力配煤方案的原则。
5) coal quality index
煤质指标
1.
The theory calculation value of blending coal quality index may tally with the practice measure value.
根据计算配煤煤质指标的加权平均值必须处于相同基准下的原则， 纠正了过去沿用的一些不正确的计算方法， 提出了计算配煤工业分析、发热量、灰熔融性和灰成分的正确的计算公式， 从而使配煤煤质指标的理论计算值与实测值更趋于一致。
6) coal bed methane index
煤层气指标
1.
