Abstract

By analyzing the overlying strata caving characteristics and properties of porous media that a heterogeneous porous media properties mined crack rectangle landings is formed in the mined-out area. Introduction of translation-diffusion equation and to simulate the flow of gas diffusion behavior; by the application of Navier-Stokes equations and Brinkman equations building face and goaf gas flow model to establish a physical model of gas flow in coal mining face. COMSOL Multiphysics numerical software for the study of the mined-out area under different ventilation mode gas distribution numerical simulation results show that: the tail roadway and high drainage roadway can improve the upper corner gas overrun problem.
