炼焦煤质量指标评价体系的研究

对我国青海、四川、新疆等地炼焦煤质量的工业指标、工艺指标、煤岩指标、焦炭显微结构组成（光学组织）和焦炭热性能进行研究，提出了一套包括挥发分、黏结指数和单种煤成焦显微结构组成评价炼焦煤质量的指标体系。该评价体系由质量控制指标、结焦性指标和揭示成焦质量指标组成。

Index system for evaluating the quality of coking coal

Based on the study of the industrial indexes, process indexes, petrology indexes, the micro structure and thermo properties of coking coal from such provinces in China as Qinghai, Sichuan, Xinjiang, Henan, and Shanxi, etc. ,this paper presents a new quality index system for evaluating coking coal which involves volatile matter, caking index, and micro structure （optical structure） of coke made from unblended coal. The index system is found to be superior than commonly-used ones in providing information about the nature of coking.
