摘　　要：针对铁矿采空区的特点,合理选择物探方法、灵活运用物探方法是准确探测采空区的关键。根据铁矿开采前后磁场的变化特征,结合开采前的物探资料,利用超低频地质遥感法探查采空区的空间分布、埋深是一种新的尝试。同时,结合其它物探方法(天然电场选频法),可相互补充、相互印正,效果更好。本文通过实例介绍了超低频地质遥感法在铁矿采空区探测中的应用效果。For the characteristics of iron ore mined-out area,a reasonable choice of geophysical methods,flexibility in the use of geophysical methods is accurate detection of mined-out area the key.According to the changes in the magnetic field before and after the iron ore mining features,combined with pre-geophysical exploration data,geological remote sensing method using ultra-low frequency probe the spatial distribution of mined-out area,depth is a new attempt,combined with other geophysical methods（natural electric field frequency-selective France） can complement each other and India are,better.This paper describes examples of ultra-low frequency geological remote sensing method in detection of iron ore mined-out area of the application results.
