The rotation mining of fully mechanized working face began in Germany in 1970s, and to the beginning of the 1980s, some mining areas in China have carried on the attempt, but the research was not so thorough enough to fail the test, so rotary joint technology for mining on ordinary mechanized mining face has not been applied in large scale in China.%综采工作面旋转式采煤20世纪70年代始于德国,至20世纪80年代初,我国一些矿区进行了尝试,均以研究不够深入而试验失败,因此普通综采工作面旋移对接式开采未在我国大范围推广应用.
