Abstract: With the steady progress of China's coal preparation sector, to operate a coal preparation plant in a safe, environmentally-friendly, highly efficient and energy-saving manner has become a common understanding.Whether the goal can be reached or not is closely related to the technologies applied.The paper presents an analysis of the state-of-the-art of China's power coal cleaning technology, the actual problems existing in such plants, as well as the current demands of such plants for technological innovation.It is hoped that through this paper, mutual technical exchange and exploration can be conducted, so as to tackle the existing problems and hence boost the level of power coal preparation technology.
