The invention discloses a room-and-pillar mining subsequent filling mining method for gently inclined to inclined ore bodies, relates to the technical field of mining, solves the existing technical problems, and comprises the following steps: step 1, determining a working face arrangement mode; 2, mining preparation and cutting roadway arrangement; step 3, stoping; step 4, filling; according to the mining method for the medium-thick ore body from the gently inclined to the inclined ore body, the process is simple, the mechanization degree is high, the productivity is large, the efficiency is high, the mining and cutting work amount is small, and collapse cannot be caused to an overlying rock layer or the earth surface after mining is completed. While efficient mining is performed, the tailing sand can be fully utilized, and the upper ecological environment cannot be affected. And the stoping of the chambers and the pillars is performed by using large mechanical equipment, so that the device has the advantages
