    • Abstract
  • In order to study the effect of the fractal characteristics of gas coal pores on gas adsorption, the pore structure of Fukang gas coal was tested by the low temperature liquid nitrogen adsorption method, the FHH model was used to calculate the fractal dimension of experimental coal samples, the adsorption characteristics of coal samples were determined by high pressure volumetric method, the relationship between the fractal dimension of gas coal and the gas adsorption performance was analyzed. It is shown through the experimental results that the surface fractal dimension D1 is positively correlated with Langmuir volume VL and negatively correlated with Langmuir pressure pL, but the correlation between the structural fractal dimension D2 and the Langmuir volume VL and Langmuir pressure pL of coal samples is not obvious. It is shown through the analysis that pore structure distribution and pore type of the gas coal affect the gas migration of the coal pores.
