As the Xingdong mine close to the urban area, the ground can not be built gangue mountain, in order to solve the problem of mine gangue lifting, the research and application of gangue processing was given, through the underground washing system, underground gangue filling system of targeted research and continuous practice, combined with the ground deformation observation and monitoring, the normal construction (structure) of the ground was ensured. The system formed a unique underground mining-selecting-filling integrated gangue treatment system of Xingdong Mine, which realized green mining and sustainable development, and provided valuable experience for mines with the same conditions.
