Research and Data Analysis of the Deep Borehole Geomagnetic Observation System in Yangjiang City,Guangdong Province
摘要
Abstract
The use of deep borehole geomagnetic observation system is the main method to solve the ground noise interference and improve the quality of geomagnetic observation.Yangjiang deep borehole geomagnetic observation system has measured the total field strength data of the earth's magnetic field.This paper will compare the measured data with the nearby mobile geomagnetic observatory in ground surface,the Zhaoqing geomagnetic reference station in Guangdong and other geomagnetic stations.The results show that the total field strength data of the geomagnetic field of the Yangjiang deep borehole geomagnetic observation system is similar to those of the nearby ground observation.When the geomagnetic field is calm or the magnetic disturbance is weak,the geomagnetic observation of the underground at 200 meters will not be affected by the induced geomagnetic field of the surrounding rock.However,when the magnetic disturbance is severe,it will be affected by a certain degree of induced geomagnetic field.Deep borehole geomagnetic observation technology effectively filters out the nearby surface of high-frequency electromagnetic interferenc,e,and to a certain extent,it also plays a repressive effect to the high-voltage DC interference of the distant China Southern Power Grid " waxy wide line".关键词
