摘　　要：依托于中核集团内蒙古二连盆地某在役砂岩型地浸铀矿山,利用可控源音频大地电磁法(CSAMT)与激发极化法(中间梯度装置)(TDIP)对砂岩铀矿地浸过程进行监测试验研究。获得了一套完整的浸出过程的CSAMT和TDIP监测数据,对这些数据进行处理和反演,获得了试验井场的地下二维反演模型、极化率剖面平面图和极化率平面等值线图,并对溶浸范围的形成和变化机理进行了研究和阐述。初步确定了一组专门针对砂岩型铀矿地浸开采的监测方法。A series of researches and tests including CSAMT and TDIP geophysics monitoring was performed in some in-situ leaching deposits in service in Erlian Basin, Inner Mongolia. A complete suite of CSAMT and TDIP data was obtained and two-dimensional inversion profile, polarization profile map and plane contour of polarizability were also taken by performing data processing and 2D inversion. The mechanism of forming and variation for leaching range was studied and elaborated. A group of monitoring methods for in -situ leaching of sandstone type uranium deposits have been preliminarily identified.
