Study of the Effect of Drying on the Pore Structure and Rate of Oxygen Consumption and Heat Release of Immersed Lignite

Figure 3

T₂ distribution and accumulated integral area of pores with different pore sizes for saturated coal after 8 h of drying. Note: sample number 1-1-Rc indicates the test result of the first sample in the first experimental group under raw coal conditions. 1-1-ad-8 h is the test result of the first sample in the first experimental group after drying for 8 h in the air environment after saturation. This figure, Figure 4, and Tables 1 and 2 are similar. (a) T2 distribution. (b) Accumulated integral area of pores with different pore sizes.
