自然崩落法放矿计划与管理系统研发与应用研究OA

The block caving is one of the most efficient mining methods for large,thick,and fragmen-ted ore bodies.However,the draw control process is strongly affected by ore fragmentation,grade mixing,and variations in geological conditions,which often results in ore loss and dilution and conse-quently constrains resource recovery and economic performance.To address these issues,a draw plan-ning and management system for block caving was developed with the aim of improving draw control efficiency and economic benefits through systematic planning,intelligent decision support,and visual-ized production management.The system was developed using a platform-plugin software architecture and a three-layer framework consisting of a presentation layer,a core application layer,and a data lay-er.It integrates three key functional modules,including scheme design,draw planning,and produc-tion management,and employs PostgreSQL with spatial data extensions to enable unified data storage and efficient access.Field application results show that the system stabilizes the daily ore grade at ap-proximately 0.32％,with intraday grade fluctuations controlled within±0.01％,and increases the resource recovery rate by about 0.5％.Based on the designed production capacity and metal price,the annual reduction in metal loss is estimated to be approximately 92.22 million CNY.These results demonstrate that the proposed system provides effective decision support for block caving draw control and exhibits strong engineering applicability and promotion potential.
