Abstract: There are many types of coal mine automatic monitoring systems, and the technical routes are not unified. The system software is relatively independent, and the data is lack of correlation. At present, field data fusion and linkage control are mostly realized by the underground fusion substation or the ground fusion platform. It is difficult to realize the unified integration and linkage control of the whole mine from the bottom perception to the ground fusion. Based on the requirements of multi-system fusion of coal mine safety monitoring system and intelligent construction of coal mine, the key problems to be solved in multi monitoring information fusion of mine are analyzed. The problems include integrated acquisition and fusion of monitoring data of personnel, machine and environment, efficient and consistent sharing of safety monitoring and control data, low code and rapid secondary development of automatic monitoring system, and integrated supervision of whole life cycle of mine equipment objects. The scheme of multi monitoring information fusion and linkage for intelligent mine is proposed. The overall framework including underground data fusion and linkage control and ground multi monitoring information fusion is constructed. This paper introduces the implementation scheme of underground data fusion and linkage control based on edge fusion substation, and expounds on the key technologies of ground multi monitoring information fusion from three aspects, which include unified technology system, unified technology architecture and data processing mechanism, and deep information fusion based on the mine object information model. Therefore, an open integrated management and control platform of multi monitoring information is developed. Based on the coal industry communication driving protocol set embedded in the scheme and the basic supporting technologies such as coal mine monitoring, control, position service, 2D and 3D GIS, and workflow engine, the following platforms can be rapidly developed: the independent software platforms for automatic monitoring system of environmental safety monitoring, mobile target positioning and coal flow transportation control, the integrated safety production monitoring and control platform and integrated management and control platform of intelligent mine. The scheme forms industry-level real-time industrial configuration software.
