Characteristics of pore structure and fractal dimension of low-rank coal: A case study of Lower Jurassic Xishanyao coal in the southern Junggar Basin, NW China
Characteristics of pore structure of low-rank were discussed. The poor development of mesopores in low-rank was observed for the first time. Characteristics of pore structure fractal dimensions were studied. The relationships between CBM accumulation and fractal dimensions were discussed.
