摘要
本文较详细地研究了徐州煤田太原组煤的显微硬度和显微脆度。首次提出了用显微硬度和显微脆度划分煤的还原类型的标准。
The microhardness and microfragility of the coal from Taiyuan formation in Xuzhou coal field were researched in detail in the paper. The demarcation line which coal type of reducibility was differentiated with the microhardness and micro fragility was first proposed.
