Surface Electromagnetic Prospecting System (SEP) contrast test in Caosiyao molybdenum mine, inner mongolia

In order to test the performance and reliability of each component of surface electromagnetic prospecting (SEP) system in practical exploration, and the overall ability of SEP system in field work, a test is conducted at Caosiyao molybdenum mine in Xinghe, Inner Mongolia, which is a comprehensive test involving each component of SEP system. Using a number of schemes, several contrast tests had been carried out, including contrast test between high-temperature superconducting magnetic sensors and coil magnetic sensors, contrast test between fluxgate magnetic sensors and coil magnetic sensors, transmitting performance contrast test among SEP, GGT-30 and TXU-30 transmitters, CSAMT contrast test among SEP, V8 and GDP-32II systems, and MT contrast test between SEP and V8 systems. This paper analyzes the test results which show that self-developed SEP system has basically reached or exceeded the level of the similar foreign products, and is competent for the practical exploration work in the field.
