Electrical anisotropic response of water conducted fractured zone in the mining goaf

Su, Benyu; Malekian, Reza; Yu, Jingcun; Feng, Xihui; Liu, Zhixin (Institute of Electrical and Electronics Engineers, 2016-07)

Based on the Maxwell equation, the occurrences of fractured zones are studied through the galvanic method. The electrical and magnetic fields are first derived in the spatial domain. To simplify the calculations, the ...
Modeling of whole-space transient electromagnetic responses based on FDTD and its application in the mining industry

Yu, Jingcun; Malekian, Reza; Chang Jianghao; Su, Benyu (Institute of Electrical and Electronics Engineers, 2017-12)

Hidden, water-abundant areas in coal mines pose a serious threat to mine safety and production. Underground transient electromagnetic method (TEM) is one of the most effective means of detecting water-abundant areas in ...
