The aim is to create and validate a model that simulates the interaction between crack propagation in rocks and fluid flow, specifically for predicting water inrush incidents in coal mines.
Developed a coupled stress-seepage-damage model based on micromechanics.
Model implemented using COMSOL code via finite element method.
Validated through axial compression-seepage tests on standard rock samples.
Predicted risk of fault water inrush in F13 fault at varying coal pillar widths of 50, 40, 30, and 20 m.
Identified water inrush channels involving fault, surrounding rock, and failed floor zone when coal pillars are 30 or 20 m.
Model provides insights into rock damage and water inrush evolution, enhancing safety in mining operations.
