Characterization of Pore Structures with Mercury Intrusion Porosimetry after Electrochemical Modification: A Case Study of Jincheng Anthracite.

47 that the range of fractal dimensions is 2.27–2.97, and the pore structure of tested anthracite coal is relatively complicated. After modification, the fractal dimensions D 1 approximately showed an increasing trend with increasing electric potential gradients, while the fractal dimensions D 2 showed a decreasing trend, which indicates that the fracture system became more complicated and the pore system became more regular after electrochemical treatment because the filled minerals in fractures are dissolved and macropores are formed.
