摘　　要：论述了旋转工作面中煤损的特点,以及如何通过改进旋转工作面的调面方式来提高煤炭回收率的方法。此法在普通的全面旋转工作面中同样适用,是一种比较经济的方法。它既能解决工作面旋转中心在反复支撑的情况下十分破碎、难以管理的问题,又能把端头的弧形三角煤基本回收。It is about the characteristics of the coal losses which working in rotating coal mining method and how to increase the system of the working rotation in the coal wining for improving the coal mining ratio observations. This method applies equally when the normal rotating coal mining method is applicable, it is a more economical way. This will not only solve the problem of the rotation center of the face was very broken in repeated supporting role and was very difficult to manage, but also will basic recovery the coal losses of the beginning.
