露天铁矿采空区综合探测方法研究与应用
|
摘要
综合运用高密度电阻率法和地震映像法对露天铁矿采空区进行探测,并对探测结果进行分析对比,弥补了单一高密度电阻率法存在探测盲区、易受干扰和单一地震映像法定位复杂的缺点,准确推测出露天铁矿生产区域地下40m范围内空区的分布特征,解决了露天铁矿地下采空区探测的难题。运用该方法,在本区域内共探测出空区3处,并划定其展布范围,为矿山的治理工作提供了可靠依据。
The high density electric resistivity method and the seismic imaging method were adopted to detect the mined-out areas of open pit iron mine,and then the results of detection are analyzed and contrasted,which will make up the disadvantages of this method,like blind detecting spot of the high density electrical method,easily being influenced,and difficult to position by the seismic imaging method.This method accurately predicted the distribution feature of the mined-out areas under the ground about 40 meters,and solves the detecting problem of the underground mined-out areas in open pit iron mine.By this way,three mined-out areas were found in this region,and the distribution range is given.All of these provide a reliable basis for management of the mined-out areas.
