Description

Technical Field

[0001] This utility model relates to the field of coal mine detection technology, specifically to an anti-interference transient electromagnetic geophysical detection receiving probe. Background Technology

[0002] Transient electromagnetic geophysical exploration (TEM) used in coal mines is a geological exploration technique that utilizes the principle of electromagnetic induction. TEM detects the resistivity of the underground medium by transmitting a pulsed magnetic field into the ground and observing the secondary induced eddy current field generated during the intervals between the pulses. This method offers significant advantages such as high resolution and sensitivity to low-resistivity materials, enabling precise detection of geological anomalies in complex environments. TEM requires a receiving probe.

[0003] However, existing interference-resistant transient electromagnetic geophysical receivers have the following drawbacks:

[0004] (1) The existing anti-interference transient electromagnetic geophysical receiver probe has a weak support and fixation function. When using the existing device, the staff need to hold the probe and point it at the designated location for detection, which may increase the workload of the staff.

[0005] (2) The existing anti-interference transient electromagnetic geophysical receiver probe has a weak adjustment function. When using it, the existing device cannot accurately detect the location to be detected, which may cause poor detection effect. Utility Model Content
