Currently, a mine refers to an independent production and operation unit for mining ores in a certain mining boundary. The mine mainly comprises one or more mining workshops (or pittings, mines, open stopes and the like) and auxiliary workshops, and most mines also comprise a beneficiation plant (coal washing plant). The mine comprises coal mine, metal mine, non-metal mine, building material mine, chemical mine and the like. Mine size (also known as capacity) is usually expressed in terms of annual or daily production. Annual output is the amount of ore produced by the mine each year. According to the size of the output, the large-sized, medium-sized and small-sized products are divided into 3 types. The size of the mine scale is adapted to the economic and reasonable service life of the mine, and only then can the capital cost be saved and the cost be reduced. In the production process of the mine, the excavation operation not only consumes most manpower and material resources and occupies most funds, but also is the production link with the largest potential for reducing the mining cost. The main approach for reducing the excavation cost is to improve the labor productivity and the product quality and reduce the material consumption. However, the uniformity and compactness of the similar material in the simulation process of the existing mine similar material simulation test system are difficult to be effectively controlled, and the accuracy and reliability of the test result are seriously influenced; meanwhile, a physical model with high precision cannot be manufactured, so that the physical model cannot be subjected to experimental research in a laboratory by adopting a similar simulation method.
