Abstract—Under bination of underground mining and The number of mines in foreign countries switching to
open-pit mining, the two excavation bodies interact with each other underground mining from open-pit mining approximately
and the movement of rock mass and surface is in a plex doubles every 20 years. Owing to their abundance of natural
state, leading to mining damage. This paper, targeting at the east resources in the United States, Canada, Australia, there is less
slope of Antaibao Mine with the joint employment of underground
necessity for underground mining in their mines. Therefore, the
mining and open-pit mining, aims to study the moving law of the
slope rock mass and the damage mechanism to the overburden of main researches focus on when the switch happens. While many
the goaf by numerical simulation. The study results are in favor of domestic large and medium-sized mines have of the need for
systematically summing up the possible damage model for slope in deep mining, China is facing the probl
