地面三分量磁测的观测误差分析
Observation Error Analysis of Three-magnetic Component Measurement on the Ground
【摘要】 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。
【Abstract】 Direct measurement of the whole space for the total magnetic field,magnetic declination and magnetic inclination(or X,Y and Z),namely the three-component parameters are mainly used on the basic network of the seismic stations in our country.However,the movable measurement of the three-component has seldom been applied to.As to mineral exploration,movably measuring three-component of magnetic field can expand the application scope of magnetic exploration,and even can still be applied in tunnels and other special areas.Also,it can overcome the singleness of the measurement parameter and improve the magnetic information quantity,which is helpful to the interpretation.This paper summarizes the model test of using FVM400 three-component magnetometer,and focuses on analyzing the impact of measurement procedure on the quality of magnetic data and the considerations of the magnetometer used in the field.
