description The invention discloses a horizontal strip type mixed filling mining method applicable to three-underground orebody mining.The method comprises the steps that an orebody is divided into multiple subsections in the inclining direction, the interior of each subsection is divided into multiple ore chambers in the extending direction, the ore chambers in the same subsection are subjected to backstoping and then filled with the same material of waste rock or cement, the ore chambers in different subsections are filled with different materials, and a horizontal strip type mixed filling body is formed.Compared with a traditional filling mining method, the horizontal strip type mixed filling body formed through the mining method has the effect of better controlling deformation of an overlying rock mass.According to the horizontal strip type mixed filling mining method applicable to three-underground orebody mining, a crown pillar only needs to be arranged on the uppermost portion of the middle section height, crown p
