Abstract Large-scale cement raw material mines and sand-gravel raw material mines with an annual output of more than 10 million tons have the characteristics of large investment, high operating costs, large mining area, high mining depth, complex mining technical conditions, large changes in ore quality, and high requirements for surrounding environment and supporting conditions. Combined with the design of large-scale mines, it is proposed that the selection of large mines in the early stage should fully evaluate the important technical factors such as mining area and surrounding environment, ore quality, mine reserves reduction, mine geological conditions, mining conditions, and comprehensive utilization of resources. At the same time, it is necessary to carry out reasonable mining by areas，reasonably balance the advanced relationship between mining and stripping, reasonably select the development and transportation system, scientifically determine the parameters of the chute system, rationally allocate mining equipment, make full use of mining pit with waste filling, and rationally design waste dumps, which provide technical measures for large mine construction.
