以金山店铁矿崩落回填区为例,建立了崩落回填区渗流与应力耦合的数学模型,分析了渗流场与应力场耦合特性。模拟结果表明：在巷道附近渗流速度较大时,通过巷道边界的渗流量为1.3×10-3 m3/（s.m）;考虑耦合比不考虑耦合总水头值总体上是减小的,特别是在底部区域,影响更为明显;耦合对应力场也有一定的影响;总水头值随着耦合系数β的增加而逐渐减小。

Taken the backfill area of caving mining of Jinshandian iron mine as the example,the mathematical model for seepage and stress coupling in backfill area of caving mining was set up,coupling characteristics of seepage and stress field were analyzed.Simulation results indicate that seepage velocity is higher around laneway,seepage quantity through laneway boundary is 1.3×10-3 m3/（s·m）.Compared with uncoupled condition,the value of the whole head of coupled condition is reduced totally,and the influence is much obvious especially in the bottom area.Coupling has certain influence to stress field.Whole head value reduces gradually with the increasing of coupling coefficient β.
