摘要
通过分析炼焦煤生产矿井在日常煤质工作中的采制样过程,阐述了影响煤层煤样黏结指数(G值)准确判定的因素,提出采样时应科学地选择采样点位置、制样时要保证逐级缩分中煤样颗粒分布均匀。
The process of sampling and sample preparation during daily coal quality work of coking coal mine was analyzed,the factors influencing accurate judgement caking index of seam sample was discussed.It was proposed that the sampling point should be located scientifically,and the uniform distribution should be guaranteed in step of division during sample preparation.
