RIM method

Post by sun dongfeng »

I am from Beijing, China. I want to know which manufacturers have commercialized cross-hole electromagnetic instruments?
Looking forward to your reply

The RIM method is primarily used for low frequency (kHz to low MHz) crosshole imaging, primarily to detect voids in coal mines before additional mining. They also make an EM gradiometer for detecting shallow conductors. The EM gradiometer system has a passive tunable receiver and can use three different transmitter sources: small portable inductive loop antennas, portable radio tower transmitters, or existing nearby AM radio station transmitters.

Very interesting. They built their own instruments. I wish someday I have some budgets to build my own tools.

This method has many applications in China. I know Stolar Globa, but they only do some services and do not sell this equipment to China.
