中文摘要：

在强磁场干扰的调查区域，应用传统的结构面产状测量方法所测得的产状数据不真实。根据某大型铁矿水文地质工程地质调查的工作需要，总结出一套行之有效的方法，即使用通过测量巷道中线的平行参照线到地质罗盘的长边水平延伸线角来计算倾向，这样能在强磁场干扰的条件下，依旧采用地质罗盘仪来测量结构面产状，经过简单校算就可以准确确定结构面产状。

英文摘要：

In the structural plane occurrence measurement by the conventional method in the under - investigation area that is under the interference of a strong magnetic field, the data obtained are often unreal. According to the need in the hydrogeological and engineering investigation in a large iron mine, an effective method was summarized so that the structural plan occurrence under such conditions can be accurately determined, which still uses the geological compass but needs only a simple correction calculation afterwards.
