Abstract

An inclined shaft continuous feeding system for solid backfilling materials includes a surface loading system, an inclined shaft transportation system, and a downhole unloading system. The inclined shaft transportation system is arranged between the surface loading system and the underground unloading system. The inclined shaft transportation system includes a bottom unloading dumper, support guide wheels, a guide rail, a drive wheel, a reverse wheel, and a traction steel wire rope configured between the drive wheel and the reverse wheel. The present invention can realize a steady, continuous and efficient transportation of the solid backfilling materials from the surface to down hole. Moreover, the material transportation system does not wear easily, has long service life and low material transportation cost.
