摘要
使用自动煤岩测试软件进行岩相分析并对测试结果图形进行修正,指出修正后得到的标准方差不能作为衡量煤炭质量的依据,其区间含量值仅代表显示某种特性煤的大小而不是某种煤类真正含量多少,且测试数值结果存在一定误差。
The automatical coal petrography analysis software was introduced to do the petrography analysis and graphic correction of testing results in this paper, it was pointed out that the standard deviation after correction could not be used as the basis of measuring coal quality. The range of content only represented the content of coal of certain petrography property instead of the real content of certain coal types. At the same time, there were some errors in the testing results.
