宁夏固原市硝口岩盐矿是近年来在宁夏境内发现的一座大型沉积型岩盐矿，为了进一步探测地下复杂地质结构，拟采用可控源音频大地电磁法为勘查手段。经可行性试验后，使用收发距10 km、发射距1 km、测点距200 m的野外观测装置，野外数据经过圆滑滤波、静态校正及二维反演后，以二维反演剖面图为依据，结合工区地质资料及物性参数，圈定了断层的产状与形态，划分了各地质界面。经后期钻孔验证，证实了方法在本测区的应用效果。

The Xiaokou rock salt deposit of Guyuan is a large sedimentary deposit found in recent years in Ningxia. In order to detect underground complex geological structure, the authors tried to use the controlled source audio - frequency magnetotelluric sounding method as a exploration means. After feasibility test, the observation device was used as follows: the transceiver distance was 10km, the emitter distance was 1km, and the site distance was 200m. After smooth filtering, static correction and 2D inversion for row data and on the basis of the picture of 2D inversion profile, in combination with the physical parameters and geological data in the survey ar?ea, the authors conducted interpretation of the subsurface geological structure. Drilling at the later stage verified the application effect of this method in the survey area.
