Abstract The No.8468 face of Yangdong mine of Jizhong Energy Fengfeng Group is a fully mechanized working face of No.4 coal seam. Because the working face is greatly threatened by confined water, in order to avoid the occurrence of water outburst accidents during the mining process of the working face, the mine has carried out comprehensive geophysical exploration on the working face. During the geophysical exploration work, the technical requirements of on-site working conditions were strictly followed to ensure the construction quality and the reliability of data acquisition. At the same time, the geophysical conclusions were combined with the actual geological data to achieve good geophysical exploration results. This paper draws on the working arrangement and analytical method of the comprehensive geophysical exploration, which can provide technical guidance experience for the geophysical exploration work in adjacent working areas. The study is of great significance to ensure the safe production of coal mines.
