Abstract:At present, there is no full life cycle simulation management system of TSF in China. The management of TSF design, construction, production and operation and closure mostly stay at the two-dimensional level, and there is no unified whole between each stage. This paper innovatively applies GEOPAK software to establish the whole life cycle simulation management system of TSF, and gives full play to the technical advantages of GEOPAK software in three-dimensional modeling technology, visualization technology, three-dimensional simulation technology, etc. to describe and analyze the complex process of TSF engineering construction and operation. The simulation management system includes design assistant, construction assistant, production operation assistant and closure assistant subsystems, which can realize the functions of three-dimensional simulation, fine operation and visual management. At the same time, the model and operation results of each subsystem can be called and checked each other, so as to simulate and manage the whole process of TSF life cycle, It fills the technical gap in this field in China.
