摘　　要：1987年10月27日—11月11日中匈地球物理工程者在匈牙利一号铝土矿区的13个钻孔中，使用中国地质勘查技术院物化探研究所研制的JWQ—3型单、双孔电磁波仪进行了试验。铝土矿的围岩为白云岩（石灰岩），矿与围岩的高频电性有明显的差异。通过初步应用，本方法可在间距为20—30m的铝土矿内的钻孔间探明白云岩体的存在；或在间距为40—60m的白云岩钻孔之间发现较大的铝土矿盲矿体。Abstract The JWQ-3 Type single-aperture and double-aperture electromagnetic wave instruments developed by Institute of Expleration Geophysics and Geochemistry, China Academy of Geological Exploration Technology, were tentatively used by Chinese and Hungarian geophysicists in No. 1 bauxite district of Hungary from October 27 to November 11, 1987. The wall rocks of the bauxite is dolomite (lime stone), and there exists apparent difference in high-frequency electricity between ore and wall rock. Preliminary application shows that this method can disclose dolomite body between boreholes at an interval of 20-30m within the bauxite depesit, or discover fairly large blind bauxite orebody between dolomite boreholes at an interval of 40-60m.
