摘　　要：对采空区遗煤状态进行实测与分析 ,并采用有限元数值模拟方法求解综采放顶煤工作面采空区遗煤内的风流运动规律的二维非线性渗流方程 ,从而较为有效地反映出采空区遗煤中风流压力和速度分布情况 ,结合实例 。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.
