Abstract: Upward type horizontal sub-level cemented filling mining method has been adopted in 14-5# ore body of Laochang tin ore, but a series of problems exposed. Through adoption of layering open stope afterwards cemented rockfill mining method, slope structural parameters were optimized, problems were solved and good economic effects was obtained.
