摘　　要：磁电法作为一类特点明显的电磁勘探方法,在资源探测中具有一定的应用优势与前景.本文结合磁电法勘探的特点,通过理论计算、硬件设计与野外试验分析,对磁电法仪器研制与方法应用中的若干关键技术进行探讨,包括:研制仪器需注重灵敏度、精度,方法技术应用中频率选择、测量装置方式、线缆布设方式等关键技术及其影响.研究结果可为磁电法仪器开发和方法应用提供一定的参考启示作用.As an effective and efficient electromagnetic method, magnetometric resistivity method has certain application advantages and prospects in resource exploration. It has been extensively used worldwide, however, it is unfamiliar in China. In order to solve the problem that it is difficult to obtain IP information in the bad-ground areas resource exploration, we study magnetometric resistivity and magnetic induced polarization technology including method,instruments, and application. Combining the characteristics of magnetometric resistivity method prospecting, through hardware design, theoretical calculation, field test and other means, some key technologies in the development and application of magnetometric resistivity method instruments will been discussed.Include:high sensitivity and accuracy for developing instruments, how to rational selecting frequency and layout measuring device mode and cable mode. The research results can provide some reference and inspiration for the development and application in magnetometric resistivity method prospecting.
