Abstract: Against the backdrop of digital mine construction，the traditional open-pit mine road sprin⁃ kling mode has shortcomings such as low operation efficiency and severe water resource waste，and is diffi⁃ cult to meet the needs of efficient operation and maintenance as well as green development of modern mines. However，automatic control technology evolves toward intelligence，networking，and centralized manage⁃ ment and control，providing key support for the upgrading of sprinkling operations. Based on this technolo⁃ gy，an intelligent sprinkling algorithm suitable for open-pit mine roads is proposed，and an integrated sys⁃ tem of "monitoring stations-management platform- on-board terminals-APP" is constructed.Environmental monitoring stations are deployed along mine roads to collect real-time road condition and environmental in⁃ formation，which is then aggregated to the central control platform. Through the algorithm，accurate calcula⁃ tion of sprinkling points and optimal route planning are completed，realizing the linkage between fixed sprin⁃ kling and mobile sprinkling，intelligent day-and-night scheduling，dynamic optimization of sprinkler truck routes，and automatic control of the fixed sprinkling system.Verified by actual mine engineering，the system has feasible functions and can effectively improve the efficiency of sprinkling operations and the utilization rate of water resources，which provides practical reference for the intelligent upgrading of road operation and maintenance and efficient resource utilization in similar open-pit mines.
