摘要
本文应用显微镜,从煤岩组分、煤岩类型、显微结构和显微构造特征上,获得构造煤突出危险性的初步定量指标。为了表征构造煤的抗破坏性,对构造煤还进行了显微硬度测定。并采用顺磁共振法,从煤的自由基浓度方面判别突出煤与非突出煤的区别。
In this paper, the author gained preliminary quantitative index of the tectonic coal bursting risk from the characteristics of macerallithotypemicrotexture and microstructure under microscope. In order to demonstrate the anti-destructiveness of tectoniccoalstheauthor moreovercarried out microhardness determination on tectonic coaland defermined the disfinction between bursting coal and non-bursting coal in free radical concentration of coals by the paramagnetic resonance method.
