Abstract: Based on the actual mining geological conditions and development and mining status of Xiaohuigou coal mine, and aim for building a model green mine with zero gangue discharge in Shanxi Province, The overall plan is put forward by analysing the existing technology and the prediction of gangue output, which determines to adopt the fully-mechanized filling and coal mining technology to solve the problem of about 0.87mt gangue produced in each year, and make a profound study on the core problems of gangue filling mining system. Finally, the corresponding technical support measures are formulated for some possible problems. Through the design and research, the zero discharge technology system of gangue in the full life cycle of Xiaohuigou coal mine is established, which provides reference for the treatment of gangue in similar conditions.
