ABSTRACT
The unmanned face mining is an important way to deal with the mining technique for the thin coal seam. Because such the problems as the roof-control and the automatic control of the safe equipment have not been solved, the development of the unmanned mining face has been protected. China is the first country to realize unmanned mining with the full-mechanized plow successfully. The roof-control, the safe equipment automatization control and the thin or low seam producing have been realized efficiently. It pushes the development and progress of the unmanned mining technology in China and lays the foundation for thick or medium-thick coal seam mining with full-mechanized unmanned working face.
