An accurate and reliable mathematical model for water inrush can help ensure operational safety in coal mines.
In this study, a numerical model for water inrush caused by collapsed columns that couples mechanical rock deformation with flow in porous media based on a fractal treelike fracture network was developed.
The proposed model considers collapsed columns and mining damage zones as fractal dual-porosity media.
The proposed model was validated against two sets of field data, and the results showed that dynamic changes in the non-Darcy coefficient could be used to identify the occurrence of water inrush, which can be employed to improve mining safety.
