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.

本文以山东省王楼板13301断层为研究对象。建立了三维耦合流体力学模型。研究了初级不透水断层滞后突水。通过模型试验研究了采矿扰动下位移场、应力场和应变场的时空演化特征。得到了反应断层激活的多物理场演化规律。根据案例建立了相应的有限元模型。通过数值模拟研究断层饱和度和渗透率的演化。对两种研究方法的结果进行了比较和验证。断层滞后突水可分为五个阶段。
