Human-machine Interaction (HMI) system plays a crucial role in borehole-to-surface electromagnetic surveys. In electromagnetic transmission system, real-time monitoring ability about transmitted parameters and states has benefit to prospect accuracy and efficiency improvement. The aim of this study is to develop a HMI software applied to borehole-to-surface electromagnetic transmission system. The HMI software programmed by C language controls transmission system to achieve several main functions, such as frequency transmission, transmission mode alteration, GPS time adjustment, RTC time display and battery power monitoring. From 2009 to 2010, there are four prospecting experiments did for this software. One is in the indoor laboratory, and the others are on the different mineral districts.
