Abstract

Microstructure test of lignite in Huainan Panyi Coal Mine by mercury intrusion method. According to the proportion of accumulated pore volume fraction in different radius range of coal, the pore size is classified. The pore structure characteristics of lignite at different temperatures are obtained by using the mercury retreat curve: with the increase of temperature, the trend of macropore growth is obvious. Based on the fractal dimension calculation principle of pore structure, the fractal dimension of various kinds of pore is calculated by linear regression: The fractal dimension of small pore is bigger than that of medium pore and large pore, which indicates that the pore structure of small pore is not uniform and the distribution of coal pore is dispersive at this stage.
