Abstract: Aiming at the controversy about definition, feasibility and realization of the unmanned mining in fully- mechanized coal mining face, this paper clearly pre sented a definition of unmanned mining in fully- mechanized coal mining face, and expounded the internal connections and differences among unmanned mining, intelli gent and automatic mining. This paper also analyzed the technical and non- technical influence factors of unmanned mining, and proposed the two steps about the reali zation of unmanned mining: first remote- controll mining and second intelligent mining. The case of Huangling Mine No.1 showed that remote- controll mining was an ef fective method of unmanned mining in fully- mechanized coal mining face, and had the application value of promotion in thin and relatively thin seam where the geologi cal condition was good.
