Abstract：In order to solve problems of the land subsidence and the environmental pollution of gangue,the ground gangue vertical feeding system was established by the feeding well,material storehouse,buffer device,and alarm system of whole warehouse and so on,and then ap-plied it into practical engineering.The field test results showed that it could well meet the amount of filling gangue of a working face in one cycle when the inner diameter of feeding tube was 486 mm,diameter of the material storehouse was 5 m,and the height was 15 m.It could effectively reduce the impact of filling gangue to material storehouse by using umbrella buffer.The actual daily filling gangue reached at 2 000 tons.The system solved the problem of environmental pollution resulting from gangue on the ground,and controlled the land subsid-ence effectively,which realized the harmonious development of the mine and ecology.
