Abstract: “Safe, green, intelligent and efficient” has become a consensus goal for open-pit mining worldwide. Throughout the history of mining development, the unclear mechanisms and geological conditions of mining accidents, as well as the unclear threat of disasters, are the main reasons for the occurrence of mining safety accidents. Firstly, based on the current production status of open-pit mines, the types of hidden disaster causing factors in open-pit mines were summarized and analyzed. The safety impacts of open-pit mining were briefly explained from four aspects: geological structure, hydrogeology, adverse geology, and fire. From the initial stage of detection technology to the intelligent detection stage, the evolution path of hidden disaster causing factors detection in four stages of mining geological exploration technology has been summarized. Secondly, based on the theory and technical system of detection technology, the mining exploration technology was classified and classified, and the detection methods for hidden disasters in open-pit mines were discussed and analyzed from four aspects: technical advantages and disadvantages, current research status, current application status, and future development direction. Then, from three perspectives: technological bottlenecks, application barriers, and management pain points, the current methods for detecting hidden disaster causing factors were summarized, including accuracy, coordination, economy, periodicity, interpretability, deficiency, and reliability, which pose multidimensional technological bottlenecks and cutting-edge challenges. Finally, from three aspects: the construction of a multi physics field collaborative inversion technology system, the innovation of intelligent perception and early warning technology paradigms, and the collaboration between standard systems and green technologies, a multimodal fusion and intelligent evolution path for hidden disaster detection technology in open-pit mines is proposed to help China's open-pit mines develop steadily towards a high-quality stage.
