In-hole Transient Electromagnetic Instrument
1. In light of the transient electromagnetic method, the resistivity distribution characteristics of the surrounding medium of the hole are obtained by receiving signals in the excitation hole of the roadway for the purpose of ascertaining the abnormal situation around and in the front of the hole. With this method, one hole provides multiple inputs. It integrates the functions of inclination surveying and depth sounding while drilling;
2. It is applied to hidden danger detection in mines, tunnels, water conservancy works, subways and other fields, and can also be used in the field of resource exploration;
3. As a new generation of intelligent geophysical prospecting equipment, it has Internet of Things access and cloud computing etc.
