Aiming at the fully-mechanized solid filling mining technology in"three-unders"coal mining face,the paper analyzes the reasonable filling-material selection and the technology of transporting the gangue and other filling materials continuously and efficiently to the working face-vertical feeding system. The application results of Jining Huayuan Mine and other several mines show:the system can liberate"three-unders"coal,improve the mining recovery rate and greatly prolong the service life of the mines;the gangue in digging is disposed directly under-ground,which has reduced the mine auxiliary hoisting pressure;it has solved the problem of en-vironmental pollution and damage caused by the gangue stacked on the ground.
