| Abstract: | After measuring and analyzing the state of coal in the gob,the 2Dnon-linear infiltration equation of airflow in gob is numerically simulated by finite element method.The establishment and solution of the numerical model are also introduced in this paper.The simulation results not only effectively indicate the distribution of air pressure and velocity but also give the relation between spontaneous combustion region and intake quantity of working face. |
