Blast Performance Twin Data Integration Schema (JSON Schema)

The Blast Performance Twin Data Integration Schema bridges domain-specific blast engineering practices with modern digital twin architecture. It formalizes how heterogeneous data—such as drill hole coordinates and deviation logs, explosive loading parameters (type, density, stemming), initiation timing sequences, high-speed camera-derived fragment size distributions (via Rosin-Rammler analysis), and post-blast muck pile LiDAR scans—are modeled, normalized, and semantically linked within a unified JSON-based payload. Central to the schema is the concept of 'blast event provenance', which captures traceability from design (e.g., blast design software exports) through execution (e.g., electronic detonator firing logs) to verification (e.g., fragmentation image analysis metadata). Validation rules enforce unit consistency (e.g., all lengths in meters, pressures in kPa), temporal precision (ISO 8601 UTC timestamps with microsecond resolution), and spatial referencing (WGS84 or local mine grid with CRS identifier). Furthermore, the schema supports versioned extensions for emerging modalities—such as acoustic emission signatures or drone-based thermal imaging of post-blast rock stress patterns—ensuring forward compatibility while maintaining backward validation integrity. Its implementation enables real-time ingestion pipelines, automated KPI derivation (e.g., weighted average fragment size, powder factor efficiency), and closed-loop feedback to blast design optimization algorithms.
