摘要：

Fully mechanized mining (FMM) technology has been applied in Chinese coal mines for more than 40 years. At present, the output of a FMM face has reached 10-million tons with Chinese-made equipment. In this study, the new developments in FMM technology and equipment in Chinese coal mines during past decades are introduced. The automatic FMM technology for thin seams, complete sets of FMM technology with ultra large shear height of 7 m for thick seams, complete sets of fully mechanized top coal caving technology with large shear height for ultra-thick seams of 20 m, complete sets of FMM technology for complex and difficult seams, including steeply inclined seams, soft coal seams with large inclination angle, and the mechanized filling mining technology and equipment are presented. Some typical case studies are also introduced. Finally, the existing problems with the FMM technology are discussed, and prospect of FMM technology and equipment applied in Chinese coal mines is put forward. © 2014, The Author(s).
