Abstract: With the increasingly strict national regulations on mine safety management,the contradiction between safety mining assurance and resource demand assurance needs to be addressed urgently. The trend of achieving large-scale,continuous,and fundamentally safe mining through mechanization,automation,and intelligence of mining equipment has become the main direction for the future development of mines. Currently,significant progress has been made in the research on intelligentization of individual equipment for underground mining. However,there is still a lack of research on the coordination of multiple processes and equipment in mining. Therefore,by integrating the production process,equipment configuration,organizational management mode,and actual resource conditions of the Zijinshan Gold and Copper Mine underground mining,a multi-equipment collaborative intelligent mining system,including the main production processes of excavation,transportation and crushing has been constructed. Through research on equipment selection and upgrading,communication and positioning system construction,and multi-equipment collaborative system construction,unmanned collaborative operations of excavation,transportation, and crushing equipment in underground mines have been achieved for the first time in China. The application results of the system show that the unmanned operation efficiency of the multi-equipment collaborative intelligent mining system can reach approximately 70% of the actual operating efficiency,meeting the basic requirements of mine production. The main factors that restrict the system operation efficiency include processes,design standards and collaborative control,which are also the main directions for future research on intelligent mining equipment. The successful implementation of the multi-equipment collaborative intelligent mining system in the Zijinshan Gold and Copper Mine provides a solution to enhance the safety and efficiency of underground mining operations and is of great significance for promoting the application and research of deep intelligent equipment.
