Abstract: To address the challenges of roof water hazard prevention caused by the superposition effect of water-conducting fracture zones in stratified coal mining, as well as the limitations of the existing transient electromagnetic method (effective detection depth of 100 m, inability to cover the 184 m thick Luohe Formation aquifer; 100 m blind zone in the 300 m working face; data distortion rate >35%; only one-dimensional inversion) on exploration and monitoring accuracy, this study proposes a three-dimensional high-density electrical method for mine exploration. Combining the theory of stable current fields in full space and the resistivity characteristics of coal-bearing strata, with the 2501 working face of Shaozai Coal Mine as the research object, the study tackles three core issues: the "static-dynamic" transformation mechanism of roof aquifers, dynamic monitoring technology for mining-induced water conditions, and a prevention system for the superposition effect of water-conducting fracture zones. A three-dimensional electrical visualization system for coal mines is constructed to reveal the water migration patterns in stratified coal mining, providing a new technical model for safe deep coal mining. The findings indicate that this technology can ensure safe production in the Shaozai mining area and advance coal mine water hazard warning technology from two-dimensional planar detection to three-dimensional dynamic monitoring.
