Research on multi-objective and multi-level collaborative modeling of large complex old mining area

To address the comprehensive management and development needs of large,complex,and aging mining areas,this study proposes a multi-objective, multi-level collaborative modeling method, which is applied to the Fushun coalfield. By integrating diverse information sources,such as mining geology and engineering data,a comprehensive database was established to support the construction of geological and engineering models. These models are dynamically integrated to form collaborative models that can be tailored to varying objectives and levels of detail based on actual requirements. The modeling process emphasizes a multi-objective approach encompassing management,simulation,integration,and development,while supporting multi-level representations for different applications. Results demonstrate that the collaborative model accurately reflects the characteristics of the mining area and provides a scientific foundation for effective management and future development. This modeling method offers robust technical support and valuable guidance for managing and developing large,complex,and older mining areas.
