Abstract Fault is a common fault structure in coal mine strata. The existence of fault has a great influence on the production of coal mine. In addition to the influence on the production schedule and yield of coal mine, it also directly threatens the safety production of coal mine. This paper took No.4326 face of Sanyuan Coal Industry as the research object, and used geophysical and drilling comprehensive detection technology to detect and verify DF1 normal fault. The detection results showed that the DF1 fault was a non-water-conducting fault, and the location of the DF1 fault was re-implemented. And the scope and occurrence of the DF1 fault were clarified, and the potential safety hazards were eliminated to ensure the safe mining of the coal mine. The study was of great significance to safety production.
