全空间直接测量地磁总场、磁偏角和磁倾角(或X、Y和Z)三个分量参数,在我国主要是应用于地震台站的基本台网中,而移动式的三分量测量还基本没有得到应用。但从矿产勘查方面来说,移动式的测量磁场三分量可以扩大磁法勘探的应用范围,即使在坑道等特殊的地区也可以得到应用。它克服测量参数的单一,提高磁测信息量,有利于资料的解释。本文是对使用FVM400三分量磁力仪进行模型试验的总结,侧重分析了测量程序对磁测数据质量的影响因素和野外工作主要注意事项。
In the whole space, the three components of geomagnetic total field, magnetic declination and magnetic dip (or X, Y and Z) are measured directly in our country, which are mainly used in the basic station network of seismic stations. The mobile three-component measurement Basically not been applied. However, in the field of mineral exploration, the mobile three-component measurement of magnetic field can expand the scope of magnetic exploration, even in the tunnel and other special areas can also be applied. It overcomes the single measurement parameters, improve the amount of magnetic information, is conducive to data interpretation. This article is a summary of the model test using the FVM400 three-component magnetometer, focusing on the analysis of the impact of measurement procedures on the quality of magnetic data and field work of the main considerations.
