Ground-air frequency tipper sounding exploration device and method

Abstract

A ground-air frequency tipper sounding exploration device comprises a ground transmitting device which is one or more grounding long wire sources, the wire sources are perpendicular to the direction of a measuring line, and measuring areas are arranged on the two sides of a transmitting area and are arranged in an S shape along the measuring line; the aerial magnetic field three-component measuring device is used for measuring three components Hx, Hy and Hz of the magnetic field, and a tipper is obtained through the ratio of a vertical magnetic field to a horizontal magnetic field; and the remote control system is in communication connection with the aerial magnetic field three-component measurement device, and records the position coordinates and elevation of the actual measurement point and the orientation of the measurement system. According to the invention, the influence of the electric dipole distance of the emission source and the magnitude of the current on the response rule of the tipper is small, the influence of the current on the electromagnetic response is reduced, the problem of high-power emission of ground-to-air electromagnetic exploration is solved, the feasibility of the ground-to-air electromagnetic exploration technology is improved, and the cost of field exploration is reduced; and meanwhile, the tipper is slowly attenuated in the air, so that a larger effective detection area is provided for a ground-air frequency tipper sounding method.

Description

technical field [0001] The present invention relates to the field of geophysical prospecting, and in particular to a ground-space frequency diptron sounding exploration device and method. The influence of the current on the electromagnetic response overcomes the high-power emission device problem of the ground-air electromagnetic prospecting, improves the feasibility of the ground-air electromagnetic prospecting technology, and reduces the cost of field exploration; at the same time, the attenuation of the dips in the air is slow, which It provides a larger effective detection area for the ground-space frequency dipson sounding method. Background technique [0002] With the continuous development of the economy, there is a huge contradiction between the supply and demand of mineral resources and mines. In the face of the current severe mineral situation, the country has clearly stated that it will break through the current prospecting bottleneck and point the exploration dir...

Problems solved by technology

[0007] However, the above-mentioned ground-space electromagnetic method mainly has the following problems in its application: (1) the signal-to-noise ratio is low, and the reflection of the underground electrical structure is not obvious; (2) it is mainly aimed at the single-component signal research of the magnetic field, and the magnetic field is not fully utilized. (3) The magnetic field signal decays quickly, and the detection area is limited
