Abstract：The mathematical and physical model of gas diffusion through coal particles under the third kindboundary condition was founded and its analytical solution was obtained by mathematical and physicalmethod. The measurement method of gas diffusion parameters was introduced and a measurement examplewas given. The results show that the Biot's criterion of mass transmission can reflect the characteristic of gasdiffusion through coal particles, the Fourier's criterion of mass transmission can represent the dynamic fea-ture of diffusion field varying with time. This model includes the traditional one under the first kind bound-ary condition, so it is of wider significance.
