Introduction and Analysis of Geo-electrical Observation System in Underground Well at Tianshui Station

We introduce the field layout,measuring items design,the installation technology specification and the construction essentials of geo-electrical observation system in underground well in Tianshui Station,then compare and analyze the observed data between original observation and new system.The result shows that application of the geo-electrical observation system in underground well can improve the signal-to-noise ratio and ease the confliction between the land of geo-electrical observation and the economic construction.Given the situation that the geo-electrical observation environment is interfered by economic construction increasingly,the geo-electrical resistivity observation in underground well is a new way.
