Popis:	Based on the analysis of the effect of underground closed explosion on geological bodies, a physical model of underground seepage of closed gas explosion is obtained. The model considers the changes of porosity and permeability due to crushing, fragmentation and fracturing of the surrounding body caused in the underground closed explosion zone. The relationship between the proportional radius and porosity, laminar permeability and turbulent permeability are established, respectively, based on the experimental data. The seepage parameters of different zones are obtained accordingly. The law of the pressure field and velocity field of the gas in the geological body and the law of the migration of the explosive gas in the geological body are analyzed using adimensionless finite difference method.
