Abstract EN
Water inrush disasters in mining frequently occur under the influence of confined water-bearing fault zones.
Therefore, investigating the fault water inrush mechanism is necessary to reduce the number of occurrences of this type of disaster.
In fault zones, the rock is highly fractured, and the mechanism of water conduction is complex.
In this research, the seepage mechanism of fractured sandstone in fault zones is studied through experiments, and the results indicate that the permeability coefficient of fractured sandstone depends on the axial stress and particle size.
The relationship between the permeability coefficient and axial stress was an exponential relationship.
Then, a water-rock coupled model is proposed based on the experimental results, which considers the different water flow patterns during water inrush disasters.
Finally, a numerical simulation combined with the water-rock coupled model is conducted to investigate the fault water inrush mechanism of a case study, and the results reveal that when water inrush disasters occur during mining, two types of conditions are required.
One is that the connection among the fractured zone of the coal seam roof, fault fracture zone, and aquifer fails, and the other is that the connection among the fractured zone of the water inrush prevention pillar, fault fracture zone, and aquifer fails.
This study contributes to an increased understanding of the mechanism of water inrush disasters and the design of water inrush prevention pillars.
