Abstract

Driven by the demand for "efficiency, reliability, and traceability" in volume data for mine inventory and production monitoring, dense linear laser scanning arrays have emerged as a pivotal technical approach for acquiring stockpile volume due to their non-contact measurement capability and high-density sampling. Based on a systematic review of domestic and international research, this paper starts from system configurations and engineering workflows to summarize the key methods and applicable conditions across various stages, including data acquisition, calibration and synchronization, point cloud quality control, stockpile segmentation and bottom surface modeling, surface reconstruction, and volume calculation. Furthermore, the error sources and stability-influencing factors of volume estimation strategies—such as mesh-based, grid-based, and voxel-based methods—are critically evaluated. Integrating typical application scenarios like concentrate inventory, this study further analyzes the main operational factors affecting measurement accuracy and repeatability, proposes optimization strategies for workflow, and suggests evaluation metrics for engineering deployment. Finally, the development trends of array-based scanning toward online operation, automation, and standardization are prospected. This paper aims to provide a comprehensive reference for the design, implementation, and application promotion of non-contact ore volume measurement systems.
