Product Description

Electric And Magnetic Fields Exploration Transient Electromagnetic TEM Equipment For Deep Water and Mineral Exploratio

 

 

Transient electromagnetic method (TEM) is based on the principle of electromagnetic induction and adopts the time-domain electromagnetic detection method excited by artificial field sources. The electrical source mode sends pulse signals to the ground, the ground is excited to generate a transient electromagnetic field, and the conductive geological body is induced to generate eddy currents to generate a secondary field.

 

Application:

 

1. Tunnel advanced detection

2. Exploration of geological structures around tunnels and roadways, detection of structural distribution of mining areas on the ground, and water content of structures;

3. Exploration of concealed water-conducting structures during excavation;

4. Detecting the burial depth and ore-bearing structure of benign conductive ore bodies, other engineering exploration and environmental exploration;

5. Detection of mineral veins in underground mines;

6. Structural detection and metal pipeline detection around underground caverns;

7. Exploration of water inrush sources in goafs and abandoned small coal kilns, and exploration of collapsed columns.
