The paper aims at studying the influence of rules of transparent agent infiltration of coal seam on coal seam gas diffusion.With coal particles in Gecun village, Henan Province as research object, it makes use of adsorption and desorption experiments in high pressure and variable temperature for isothermal and desorption experiments that is based on three common transparent agents, fenton reagent, acetic acid and hydrochloric acid, comparing gas of coal particles before and after infiltration. Moreover, the thesis is on the basis of the new diffusion model of dynamic diffusion coefficient and applies MATLAB software to programming procedure for calculating the original diffusion coefficient D0 of the gas desorption experiment and its attenuation coefficient β. The experimental results are as follows: transparent agents can inhibit gas adsorption of coal particles, and the inhibitory effects of these transparent agents grow stronger from acetic acid, hydrochloric acid to fenton reagent; transparent agents can promote gas diffusion of coal particles, and the inhibitory effects of these transparent agents grow stronger from acetic acid, hydrochloric acid to fenton reagent; transparent agents in coal sem can mitigate outburst risks of coal seam gas with acetic acid the best effect.Downloads
