Application of EH4 Electromagnetic Imaging System in Gold Ore Exploration

Abstract

EH4 electromagnetic imaging system is relatively advanced electromagnetic exploration instrument at home and abroad with the advantage of great exploration depth, intuitive and portable etc. In this paper, on the basis of the systematical collection of predecessors' research data and combined with the present situation of domestic and foreign researches, the author introduces the working principle of the EH4 electromagnetic imaging system, field-working method, scope, and possibly, and some geological problems that may be solved in gold prospecting. Apart from this, through exploration cases of in Zhangsangou Gold mining in Heilongjiang province, Yuerya gold deposit in Hebei province and in 460 gold mine in region of Beishan of Gansu, this paper illustrates that the effect of EH4 system in gold deposit exploration is remarkable.
