Abstract: Given the extensive production process management and low level of automation or intelligence in open-pit coal mines, this paper analyzes the overall objectives of intelligent construction for such mines in China and establishes a "four-system, five-level" full-process intelligent mining system. Driven by core technologies such as multi-ring network data transmission and perception of equipment operations and the environment, the system scientifically manages work within the production cycle of open-pit coal mines by integrating mining data monitoring, real-time parameter analysis, and the execution of management decisions, thereby achieving more precise coordination across mining processes. Field application conducted at the open-pit mine of State Power Investment Corporation (SPIC) Inner Mongolia Baiyinhua Coal Power Co., Ltd. demonstrates that the system leverages multi-ring network data transmission to ensure the high-fidelity acquisition of parameter information during the production process. By employing analytical models to conduct intelligent planning for mining and loading operations and haulage routes, the system has reduced the manpower requirements of the open-pit coal mine by 31% while enhancing its production capacity. In addition, the system enables early detection and alerts for equipment and operational hazards, substantially lowering the risk of safety incidents.
