Abstract

The invention belongs to the field of aerial magnetic resonance sounding, and provides an aerial magnetic resonance underground water detecting device and method. The device comprises an aerial systemand a ground system, wherein the aerial system involves that an aerial magnetic resonance detection system main unit mounted on an aircraft is connected with an aerial magnetic resonance detection transmitting antenna and an aerial magnetic resonance signal receiving antenna through antenna towing cables; an aircraft noise acquisition antenna is connected with the aerial magnetic resonance detection system main unit; the ground system comprises a ground controller and a wireless information transceiver, wherein the ground controller sends coordinates and other detection information to the aerial magnetic resonance detection system main unit through the wireless information transceiver; the wireless information transceiver transmits information between the aerial system and the ground system. An airship, a helicopter and other aircrafts are utilized to carry a novel magnetic resonance underground water detector, and underground water in a surveying area is rapidly detected, thereby improving the detection efficiency; the limitation of the earth surface environment conditions on a magnetic resonance sounding method in the surveying area is also reduced, and the application range ofthe magnetic resonance sounding and water exploration method is further broadened.

Description

technical field [0001] The invention relates to the field of aerial magnetic resonance sounding, in particular to an aerial magnetic resonance groundwater detection device and method. Background technique [0002] Nuclear Magnetic Resonance is a direct and accurate method of groundwater detection. The magnetic resonance method can also be applied to the detection of disaster water sources such as tunnels and mines. When applied to these environments, the form of a separate antenna for transmitting and receiving is adopted, and the size of the antenna is small, so that the magnetic resonance method can be applied to underground engineering. [0003] When detecting on the ground, the multi-coil simultaneous measurement mode can be used to perform 2D / 3D imaging of the distribution state of the groundwater body. [0004] At present, all magnetic resonance detection methods are carried out on the ground or underground engineering. Due to the actual situation on the ground, there...
