    Abstract: Coal mining industry has complex geological conditions, high safety risks, frequent mine dynamic disasters such as rock burst, coal and gas outburst, which are the core problems restricting the safe production of coal mines and affecting the high-quality development of the industry. The traditional disaster prevention and control technology is mainly concentrated in the combination of local areas of the mine field and a single influencing factor, which is difficult to adapt to the complex geological environment of multi plate intersection and active tectonic activity in China. There are problems such as insufficient prediction accuracy, weak prevention and control pertinence, and imperfect technical system. In view of the above difficulties, this paper systematically combs the whole process of the introduction, adaptation, iterative optimization and independent innovation of the geo dynamic zoning theory in China for more than 30 years, focuses on the application scenarios in the field of mine safety, summarizes and sorts out the technical iteration process, core innovation achievements, engineering application achievements and existing technical shortcomings of the theoretical system, and systematically improves the geo dynamic zoning research system and engineering application paradigm adapted to China’s geological characteristics. Using the research methods of theoretical innovation, technology research and development, system integration and engineering verification, relying on the theory of plate tectonics and the principle of geodynamics, breaking through the limitations of the application of Russia's primary geodynamic zoning theory, and combining the regional geological characteristics of the intersection of three tectonic domains, the development of fault structures, and the active neotectonic movement in China, we carried out multi-dimensional and multi-level technological innovation and practice optimization. At the basic theoretical level, the "three conditions" criterion for the occurrence of mine dynamic disasters is established, the coupling mechanism of the three core elements of geological dynamic environment, mining disturbance and prevention and control measures is clarified, the national first-class geological dynamic zoning work is completed, the national geological dynamic cell bureau is divided, the macro spatial distribution characteristics of "1-1-0" of mine dynamic disasters in China are revealed, and the differential distribution characteristics of disasters in the Tan Lu fault zone, the Qinling Dabie orogenic belt and the Sichuan basin tectonic area are clarified, which provides a theoretical basis for the prevention and control of mine disasters at the national scale. At the technical method level, three core methods, namely multi factor pattern recognition risk prediction, quantitative evaluation of geo dynamic environment and evolution analysis of coal and rock dynamic system, have been formed to break through the limitations of traditional single geological factor analysis and realize the transformation of mine dynamic disasters from qualitative research and judgment to quantitative prediction and from local analysis to overall analysis. At the system R&D level, three software systems are developed iteratively, including rock mass stress state analysis, multi factor pattern recognition risk prediction, and geo dynamic zoning information management. An integrated data integration and visual management platform is built to achieve efficient integration and intelligent analysis of geological data, structural parameters, stress data, and disaster information. In terms of monitoring technology, integrate the global navigation satellite system (GNSS), interferometric synthetic aperture radar (InSAR) surface deformation monitoring, mobile seismic network seismic monitoring, and underground fault activity dynamic monitoring technology, build a multi-dimensional monitoring system of underground and underground integration, and effectively improve the ability of mine dynamic disaster precursor information capture and risk prediction. Relying on theoretical and technological innovation, the research team has formed a patented technology and industry standard system covering disaster prediction, monitoring, prevention and control. Relevant technical concepts have been incorporated into the 2016 version of the coal mine safety regulations and the 2018 version of the detailed rules for the prevention and control of coal mine rockburst, realizing the deep integration of scientific research achievements and industry standards. By comparing the research systems at home and abroad, it is found that there are some problems in foreign related research, such as difficulty in adapting to deep compex eginneer scenes and limited engineering practicability. China’s research has formed significant technical advantages in multi factor coupling analysis, quantitative prediction, engineering adaptability, and systematic application. At the same time, identify the shortcomings of the current research, including the lack of disaster prediction accuracy under complex geological conditions, the low level of technical intelligence, and the lack of dynamic adaptive prevention and control ability. Based on the existing research foundation, in the future, we will focus on technical breakthroughs such as optimization of generalized pattern recognition algorithm, intelligent automatic division of fault block structure, accurate simulation of three-dimensional rock mass stress, and dynamic application evaluation of geo dynamic environment, integrate cutting-edge technologies such as big data, artificial intelligence, and machine learning, build an intelligent, refined, and integrated geo dynamic zoning technology system, promote the in-depth integration of geo dynamic zoning and mine dynamic disaster prevention and control technology, comprehensively improve the level of intelligent prevention and control of coal mine dynamic disasters in China, and provide solid theoretical support and technical support for mine safety production and high-quality development of the industry.
