Exhibit Summary
Wide-field electromagnetic method detection is a Interactive interactive exhibit in the Aerospace category, designed for science centers, children’s museums, discovery centers, STEM learning centers and family entertainment centers. Built as a hands-on, mechanical & electromechanical display, it turns an abstract scientific concept into direct, interactive visitor exploration, and is engineered for durable, low-maintenance, high-traffic gallery use.
Scientific Principle
This display allows the audience to gain an in-depth understanding of the technical principles and characteristics of the wide-field electromagnetic method during the actual operation via multimedia splicing screens and hands-on devices, and fully grasp the process of "using electromagnetic waves to perform CT scans on the earth". At the same time, they can discover about the mineral resource information detected by the wide-field electromagnetic method via video interpretation.
Operation
Chinese geophysicist He Jishan proposed the wide-field electromagnetic method in 2006, and officially launched a self-developed wide-field electromagnetic detection complete set of equipment in 2010. The wide-field electromagnetic method establishes a harmonic electromagnetic field via an artificial grounded field source, sends alternating currents of different frequencies underground, observes one or more electromagnetic field components, and uses wide-area apparent resistivity to detect geological targets at different burial depths. Based on the traditional controlled source audio electromagnetic magnetotellurics (CSAMT) method and the MELOS method; the wide-field electromagnetic method uses high-power, strong-signal artificial fields to suppress interference fields to improve the signal-to-noise ratio, thereby obtaining effective observation data. The advantages of the wide-field electromagnetic method include large exploration depth (up to 8,000 meters underground), anti-electromagnetic interference capability, high deep resolution, green and environmentally friendly (no blasting is required and nature is not destroyed). Compared with the traditional seismic wave method, the speed and depth of data collection are greatly improved. The Zhuxi Tungsten Copper Mine in Jiangxi Province, my country, has the largest tungsten ore reserves in the world. Due to the complex geological structure, especially in the face of the precise exploration requirements at a depth of 3,000 meters, the CSAMT method commonly used in geophysical prospecting has failed one after another. After the intervention of wide-field electromagnetic exploration technology and equipment, the fine distribution of resistivity within the 3,000-meter depth range of the mining area was obtained, clearly revealing the deep rock-controlling ore-controlling structures for the first time, providing a science basis for subsequent exploration. The displays focus on the science principles and detection process of wide-field electromagnetic method. They use an electromechanical button hands-on unit combined with a multimedia splicing screen to mobilize the audience's participation and more intuitively display the science pictures of deep ground exploration via the display screen.
