高密度电阻率法在采空区探测中的应用

Application of High Density Resistivity Survey in Mined-Out Areas

为探测地下老采空区的分布和规模,采用高密度电阻率法对齐大山铁矿地下采空区进行探测,通过科学布线和分析,较清楚地揭示了地下已开采区和未开采区的具体位置,说明了该方法探测地下采空区的有效性。与传统电阻率法相比,高密度电阻率法具有效率高、信息丰富、解释方便、勘探能力显著提高的特点。

To survey the distribution and scale of the old underground mined-out areas in Qidashan Iron Mine, high density resistivity method was used. By scientific wiring and analysis, the concrete location of both underground mined-out areas and un-mined areas was clearly exposed, illustrating the effectiveness of this method in surveying underground minedout areas. Compared with the traditional resistivity ones, high density resistivity method has the advantages of high efficiency, rich information, easy interpretation, and remarkable improved exploration ability.
