description	The invention relates to a collaborative anchoring structure for enhancing the stability of a gob-side entry driving coal pillar and a construction method, belongs to the technical field of gob-side entry driving coal pillar retaining mining, and solves the problem that an existing anchoring structure cannot meet the safety and stability requirements of a roadway. The construction method of the collaborative anchoring structure for enhancing the stability of the gob-side entry driving coal pillar comprises the steps that after an anchor net on the lower side of a roadway is laid, a first anchor cable is drilled; after drilling of a row of first anchor cables in the height direction of the lower side of the C roadway is completed, a first steel belt is used for interlocking the multiple first anchor cables in the row; in the tunneling process of the B face D roadway, the first anchor cable is installed to be located at the exposed end of the upper side of the D roadway. According to the collaborative anchoring
