Abstract: Abstract: Yimin Open-pit Coal Mine is turning its mining direction and afterwards both its truck haulage distance for overburden removal and stripping ratio will be on the rise in the coming years. Cost will be increased, labor efficiency will be cut down and evironment will be much polluted if continuely apply shovel-truck technology, In this paper,different technologies for overburden removal were briefly researched, based on the material deposition and pressure to the ground of coal mine,so as to look after the most suitable technology for overburden removal.

Key words: open-pit mine, overburden removal, economy
