With a view to ventilation network resolution and current flow diffusion, modules of resolution and one-dimensional gas diffusion in the ventilation network under unsteady state are established. Furthermore, above modules are combined organically so as to simulate coal and gas outburst incident in a mine. Simulation result fits quite close to the spot, and can give a good explanation for related phenomenon of gas outburst, which provides technique methods for research on influences of coal and gas outburst to the ventilation network.
