Risk modeling study demonstrates accurate prediction of floor water inrush in deep coal seams, suggesting improved hazard assessment under high-stress conditions.

Key Points

To develop and validate a coupled gray evaluation model to accurately assess water inrush hazards from broken coal mine floors under high geostress and water pressure.
Coupled work breakdown structure (WBS), risk-based supervision (RBS), ordered binary comparison quantization, and center-point triangular whitenization weight functions into an integrated gray evaluation framework.
Identified five primary risk indicators for the No. 2_1 coal seam in China's Guhanshan minefield: fault fractal dimensions, aquifer pressure, water-richness, destroyed floor depth, and effective aquiclude thickness.
The model successfully established index weight vectors and risk tiers reflecting the distribution characteristics of high stress and floor failure mechanisms.
Gray evolution trend predictions aligned with observed field conditions in the Guhanshan minefield, confirming the framework's reliability for deep mining floor water inrush risk assessment.
