Abstract

To address the practical challenges commonly encountered in the operation and maintenance (O&M) stage of coal preparation plants—such as prominent data silos, fragmented asset archive management, inspection work heavily dependent on manual experience, and insufficient fault early-warning capability—this paper develops a full-life-cycle O&M platform for coal preparation plants built on a BIM-based digital foundation. The research is carried out along four dimensions: digital twin scene construction, multi-source heterogeneous data fusion, business function module development, and key algorithm implementation. The digital deliverables of BIM produced in the design and construction stages are transferred to and reused in the production and O&M stage. The platform integrates the two-dimensional/three-dimensional (2D–3D) linkage of asset archives, online condition monitoring, 3D roaming inspection, closed-loop mobile maintenance and repair management, and knowledge-graph-driven fault early warning. Engineering application shows that the platform connects the data link from design to O&M, realizes virtual–physical mapping and integrated management and control of the plant's production facilities, reduces the on-site O&M workload and the risk of unplanned downtime, and thus provides a practical reference for the digital transformation of similar coal preparation plants.
