The utility model relates to a pneumatic stirring pumping drainage type mine sump silt remover and belongs to silt removing machines applied to underground metal mine sumps. The pneumatic stirring pumping drainage type mine sump silt remover comprises a gas ejector pipe, a pneumatic submersible sewage pump, a stirring barrel, a grouting pump, a grouting pipe, a main water drainage pipe and the like. The gas ejector pipe is inserted in a silt accumulation layer, through gas sprayed by the gas ejector pipe at a high speed, silt is scattered and diluted with accumulated water to form slurry, the submersible sewage pump is started for pumping the slurry, the slurry pumped out enters the stirring barrel and the grouting pump, after being pressurized by the grouting pump, the slurry is injected in the main water drainage pipe, diluted with water drainage flow in the main water drainage pipe and taken to the ground surface and enters a ground surface desilting basin to be deposited. According to the pneumatic stirring pumping drainage type mine sump silt remover, the silt can be removed without evacuation of the accumulated water in a sump and can be discharged to the ground surface without being dewatered or transported by a mine car, a transport channel is not blocked in the silt removal process, and the silt removal efficiency is high.
