模拟深部开采底板岩层的裂隙演化特征是深入探讨煤层开采底板突水规律和演化机制研究的关键，为开展深部开采高水压底板突水通道形成的模型试验，基于固流耦合相似理论，以固体材料研究为基础，研制了新型的适用于深井条件下的相似材料，提出适应该材料渗透系数的测量方法，得到不同配比对材料力学性质的影响规律，将该材料应用于底板突水模拟试验，揭示相似材料的破坏特征和深部底板突水通道的演化特征，即受采动影响开切眼处裂隙发育迅速而且程度较高，解释了此处突水概率大易发生突水危险，对解决实际工程问题具有一定的指导意义。

The simulation of floor rock fracture evolution characteristics in deep mining is the key of research on laws and evolution mechanism of water-inrush. In order to launch the model test on emergence ofwater-inrush channel in deep mining floor under high water pressure,based on the similarity theory for solid-fluid coupling and the study of solid materials,a new similar material for solid-fluid coupling was developed. This material is suitable for conditions of deep mining. The measuring method for the permeability coefficient of this material was put forward. The influence law that diverse ratios affected mechanical properties of materials was concluded. The material was applied to the simulation test of water-inrush in floor,which revealed failure characteristics of similar materials and evolution characteristics of water-inrush channel in floor. Fracture developed rapidly and with higher degree affected by mining in open-off cut. This explained the greater probability of water inrush,this place is prone to result in water inrush risk. The method has some practical meaning for coal mining engineering.
