“…In addition, combined with the conclusions of similar detection methods in the past [30][31][32], it is found that the resolution and sensitivity of TEM and CSAMTare both high, and they can meet the necessary technical parameters for exploration and detection of underground goaf. Its exploration effect depends on the device type, receiving frequency, stacking times, and other related technical parameters.…”

Due to the influence of mining technology, some coal mines will leave mined-out areas (or goafs) in the rock mass after mining. If the distribution law and influence scope of mined-out areas cannot be accurately explored and controlled, it will bring great potential safety hazards to subsequent coal mining and cause serious harm to adjacent houses, roads, bridges, railways, and so on. The unmanned aerial vehicle (UAV) aerial survey is used to accurately acquire the three-dimensional model of the slope in the key area of Yuanbaoshan open-pit coal mine, which provides basic information for the real-time visualization of the open-pit mine and the establishment of the engineering geological research profile. And the distribution of mined-out areas and water accumulation in the coal mine are investigated in detail by using the comprehensive geophysical prospecting method of the transient electromagnetic method (TEM) and controlled source audio-frequency magnetotellurics (CSAMT). Then, the borehole detection method is used to verify the goaf range obtained from comprehensive geophysical prospecting, and the results show good consistency. In addition, based on the results of borehole exploration and the comprehensive analysis of the borehole image, the instantaneous water level elevation in goaf and the development height of the water-conducting fracture zone and caving zone are concluded. Finally, the distribution of coal mined-out areas in the exploration area is obtained, and the results show that through the use of the transient electromagnetic method and controlled source audio-frequency magnetotellurics method, combined with drilling detection methods, the purpose of accurate exploration of mined-out areas in coal mines can be achieved.

“…The comprehensive electromagnetic method is more effective than a single electromagnetic method for exploring geothermal resources from various perspectives. Several research groups have conducted experiments on comprehensive electromagnetic methods, and excellent results have been achieved (Chen et al, 2011; Muñoz, 2014; Muraoka et al, 1998; Robertson et al, 2020; Smith, 2014; Spichak and Manzella, 2009; Tauber et al, 2018; Tripathi et al, 2019; Yang et al, 2009; Younis et al, 2015). However, most of the studies on comprehensive electromagnetic methods for geothermal exploration have focused on their practical applications, whereas the theoretical framework has been neglected.…”

Geothermal resource is a kind of crucial clean, renewable energy with high potential development and application. However, it involves great exploiting risks since it buried deep beneath the crust of the Earth. The location and depth of geothermal resources can be determined using the geophysical methods. Controlled source audio-frequency magnetotellurics (CSAMT) and transient electromagnetic method (TEM) have relatively high efficiency and robustness. In this paper, a simplified geothermal system resistivity model was established, which allowed TEM and CSAMT to differentiate target faults with various characteristics (resistivity, dip angle and width). Through a comprehensive electromagnetic exploration in Huairen County, Shanxi Province, China as an example, the performance of TEM and CSAMT in determining geothermal resources was evaluated. The results showed that both methods could examine the geoelectrical structures from various perspectives, and the effectiveness of comprehensive electromagnetic method for geothermal resources was presented.
