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,利用高精度磁测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可相互补充、相互印正,效果更好。通过实例介绍了综合物探方法在铁矿采空区探测中的应用效果。
It is key to the accurate detection in mined-out iron ore region to choose proper physical prospecting method. In order to find out the spatial distribution of mined-out region, precision magnetic detection is a new test, and the result will be better if other methods are combined. Based on some examples, the application of comprehensive physical method in the detection of mined-out region is introduced.
