- Abstract
This paper takes the fault of the Wang Lou panel 13301 in Shandong Province, China, as the object. A three-dimensional coupled hydromechanical model was established. The lag water inrush from primary impervious fault is studied. The spatiotemporal evolution characteristics of displacement, stress, and strain field under mining disturbance are studied by model test. The multi-physical field evolution law of reaction fault activation is obtained. The corresponding finite element model is established based on the case. The evolution of fault saturation and permeability is studied by numerical simulation. The results of the two research methods were compared and verified. The lag water inrush from fault can be divided into five stages.
