Abstract: The huge Cenozoic sediments have a strong absorption and attenuation effect on electromagnetic waves and seismic waves, and it is difficult for a single method to achieve the purpose of coal exploration. In the coal exploration of a huge Cenozoic coverage area at the western foot of the Xiangshan Mountain in Ningxia, the investment in 2D seismic exploration failed to achieve the expected purpose. In this study, the electrical method with controlled source audio magnetotelluric method as the main and direct current sounding as the supplementary method was implemented for exploration. The comprehensive method successfully delineated the range of coal-bearing strata and determined the coal-bearing nature of the coal-bearing strata. Through drilling verification and subsequent geological survey work, the comprehensive method of electro-seismic was proved to be economical and effective in coal prospecting in the area covered with huge Cenozoic sediments.
