Characterization of Coal Porosity for Naturally Tectonically Stressed Coals in Huaibei Coal Field, China
Figure 7
Relationship between and of deformed coal (a) in brittle and ductile deformed coal; (b, d) with different pore sizes in brittle and ductile deformed coals; (c, e) in log-log coordinate; mean different pore sizes; means pore size which is less than 5 nm. The subscripts 1, 2, 3, and 4 are for mesopore (10~100 nm), micropore (5~10 nm), submicropore (2~5 nm), and supermicropore (<2 nm), respectively.
