摘　　要：这里介绍的地-井TEM向量交会法是一种地-井TEM资料半定量解释方法,通过采用异常分离技术从实测资料中提取出纯异常场,运用地-井TEM的纯异常响应进行向量交会,从而达到快速、有效地确定井旁盲矿体的深度、方位及矿体距钻孔距离。The method of surface-borehole TEM vector intersection, a semi-quantitative interpretation method, has been introduced in the paper. By extracting pure anomalies from raw data with a separating technique and performing the surface-borehole TEM vector intersection with the pure anomalies so obtained, locations and attitudes of hidden ore bodies could thus be rapidly mapped.

关 键 词：地-井TEM 纯异常 向量 交会 井旁盲矿
