description The invention discloses a supporting method for hanging wall rock mass of an underground metal mining ore body, and relates to the technical field of mining, and the supporting method is characterized in that firstly, the surface of the rock mass is cleaned and subjected to surface rubbing treatment, so that the surface of the rock mass is smooth and clean and free of impurities, and a good foundation is laid for subsequent treatment work; then the surface of the rock mass is coated with a high polymer material, curing treatment is conducted, the high polymer material is attached to the surface of the rock mass, meanwhile, the hardness and toughness of the surface of the rock mass are enhanced, and therefore expansion of cracks on the surface of the rock mass can be effectively resisted; and finally, according to the size of the rock mass and the requirements of different parts, a supporting net and a ground anchor are installed, the stress of the rock mass can be evenly distributed into the surrounding rock
