The invention discloses a column type filling template beside gob-side entry retaining and a using method thereof, and belongs to the technical field of gob-side entry retaining in coal mines. The column type filling template beside the gob-side entry retaining comprises a metal bracket, a filling mold bag and a connecting device. The metal bracket is of a column frame structure formed by connecting a vertical steel pipe, a bottom transverse steel plate and a top connecting rod through a connecting device. The filling mould bag is a cylinder made of waterproof fiber cloth. The filling mould bag can be completely supported by the metal bracket and tightly attached to the metal bracket. Steel bars are additionally arranged on the outside of the filling mould bag and are called external steelbars. Split steel bars are arranged in the filling mould bag, a hook is arranged at the top of the filling mould bag, and a filling opening is formed the side, close to the gob-side entry, of the filling mould bag. The column type filling template beside the gob-side entry retaining is simple to use, and filling operation can be carried out after the external steel bars are hung and arranged on site; and by using the filling template, roadway support and maintenance costs can be effectively saved, and mine production benefits can be improved.
