| 摘 要： | 介绍了应用高密度电法与地震映象法对弓长岭露天铁矿采空区进行探测的方法技术及应用效果.地震映象法具有数据集速度较快、抗干扰能力强、勘探深度不受限制和资料处理速度快的特点.可根据波形特征和同相轴的形态推断异常顶部埋深.高密度电法对采空区的范围均有显示，但其受矿区游散电场的干扰较大.两种方法应相互补充，相互验证.

| Abstract: | High density electrical method and seismic imaging method are adopted to detect the mined-out areas in the Gongchangling opencut iron mine in Liaoning Province.The high density electrical survey may reveal the mined-out area,but it is often interfered by the electric field in the mining area.The seismic imaging method is quick in data collecting and processing,with ability of anti-interference and without limitation of detecting depth.It can infer the buried depth of abnormal based on the waveform features and the morphology of isophased axis.The two techniques should aid and verify each other. |
