ELECTROMAGNETIC EXPLORATION SYSTEM BASED ON AIRSHIP WITH ADJUSTABLE DEPTH OF INVESTIGATION

摘要

The present invention relates to an electromagnetic exploration system based on an airship with adjustable depth of investigation, in which a transmission coil (transmitter loop) and a reception coil (receiver loop) are arranged in two individual airships for flight, respectively, to enable deep depth of investigation even though the investigation is aerial exploration far from the ground, and the separation distance between the two airships in flight is differently adjusted for each measurement and a flight separation distance set for each measurement can be stably maintained during flight for the corresponding measurement, so that underground exploration data with various depths according to the geography of an exploration area can be obtained. The system comprises: a leading airship which includes a transmitter loop installed therein and flies along a configured flight route while forming a primary magnetic field; a following airship which includes a receiver loop installed therein and flies along a configured flight route while being spaced a configured separation distance apart from the leading airship, to detect a secondary magnetic field; and a measurement control device for analyzing a measurement value of the secondary magnetic field detected from the receiver loop of the following airship, to perform aerial electromagnetic exploration.
