Abstract: Aiming at the problems of low efficiency of multi-source data fusion, insufficient accuracy of three-dimensional modeling and poor adaptability of intelligent decision-making in traditional mine management, the overall architecture of “three horizontal and four vertical” is studied and designed. The “data access-processing-storage” vertical three-level fusion architecture is adopted. Relying on the three horizontal support systems of standard, safety and operation and maintenance, a “one map” management framework is formed. Through the four-level structure of equipment perception layer, data transmission layer, data center layer and business management and control layer, the intelligent closed-loop system of “perception-transmission-analysis-decision” is established, and the three-level transmission mechanism of “space-time benchmark unification → data intelligent governance → decision closed-loop control” is innovatively proposed. Through technological innovation, efficient data fusion, accurate coordinate system conversion and accurate construction of mine three-dimensional model are realized. The field application shows that the compliance rate of multi-source data “5min total factor update” is increased to 85.4%, the response delay of surrounding rock deformation prediction in kilometer-level working face is shortened to 4.2 s, and the evacuation efficiency of underground personnel is increased by 41%.
