Abstract:

As a typical process industry，the mining of underground metal mines depends on the smooth operation of the ore transportation link，and the unmanned mine truck bears an indispensable and important responsibility in the ore transportation link，so the intelligent scheduling and management of the unmanned mine truck is the key to ensure the smooth production of the mine.There are few studies on the scheduling and management of unmanned mine trucks，and it is difficult to meet the new requirements brought by the increasing degree of unmanned mine trucks.Based on the analysis of the current situation of cluster intelligent scheduling strategy，scheduling business flow，and data integration system for unmanned mining trucks in a certain underground mine in Gansu province，an integrated system platform for intelligent decision-making，automatic scheduling，and process control serving unmanned mining trucks scheduling was proposed.In response to the transformation of unmanned mining trucks scheduling mode and two traffic control challenges，corresponding intelligent scheduling strategies were designed，and the overall architecture was designed.Some functional modules were designed，including scheduling console，real-time monitoring，scheduling visualization，and production management.The system platform has been successfully applied to the mine through the intelligent transformation of the mine truck，the construction of the intelligent dispatching system，and the development of the system.The application results show that the existing traffic control problems have been solved and the dispatching efficiency has been improved by 7.18% with the help of the intelligent dispatching system with the core of vehicle end scheduling algorithm，single-lane collision avoidance algorithm and merging truck algorithm.It provides a centralized and unified management and use platform for data，breaks the information island，and greatly improves the data utilization rate.Through vocational work split and process drive，the scheduling modular management is realized.The successful application of the platform has innovated the dispatching mode，supplemented the research in relevant fields，provides an important reference for the intelligent transformation of underground mines，and also provides reference experience for the development of cluster dispatching management system platform across equipment categories and production areas.
