Abstract

Summary

Geopolariton tomography technology is a passive geophysical method that uses nonequilibrium geopolariton radiation of the Earth to explore the stress-strain state of rocks. The use of technology makes it possible not only to assess the prospects of a mining area at the design stage of work but also to control the safety of mining operations by monitoring the stress-strain state of rocks. This exploration was carried out to identify the subsurface structures of a coalfield as part of the project 2022-05-JSFU-01 commissioned by Yulin University, China. Aerogeophysical work was carried out in Shaanxi Province in northern China at the licensed area of the mining company Shenmu Shimengou Mining Co., Ltd. Shaanxi is among the provinces with abundant coal resources. An area of 2.5 km2 was investigated according to the geological task. As a result of the study, in the coalfield, at a depth of 127 m, abandoned mine workings were found. According to the obtained geophysical information, the coal mining design plans for this section of coalfield have been adjusted. Coalfield monitoring agreements were achieved. Ministry of Emergency Management published a recommendation for using geopolariton tomography to monitor the safety of underground mines.
