| PURPOSE: A mine filling apparatus for an exhausted mine through the pressurization of the ground and a sand filling method through the pressurization of the ground using the same are provided to easily and rapidly fill a mine with filler by reducing the number of boreholes. CONSTITUTION: A mine filling apparatus for an exhausted mine through the pressurization of the ground comprises a borehole(110), a filler mixing unit(120), a filler injection unit(130), an injection pipe support unit(140), and a filler diffuser unit(150). The borehole is vertically formed in a mine. The filler mixing unit is formed on the ground around the borehole. The filler injection unit forcefully injects filler to the borehole through an filler injection pipe member(133). The injection pipe support unit lifts up the filler injection unit when the mine is filled with filler and fixes the lifted filler injection unit. The filler diffusion unit widely diffuses the filler discharged from the filler injection unit. | ||||||
