Abstract: Aiming at the recovery of hanging wall ore in fixed side bench after pit closure in open pit， taking the 1 270~1 210 m fixed side bench after pit closure in Lanshan stope as an example，the hanging wall ore was recovered step by step from bottom to top by reverse mining method. The blasting vibration is reduced by layered charging and reduced the hole network parameters by small aperture drilling rig. The practical results show that it is feasible to recover the fixed side step hanging side ore by reverse mining method under the condition of ensuring the stability of the slope in the mining area by selecting reasonable mining technical parameters and backfilling the inner dumping slope toe in the mining area. The scheme has reference significance for similar mines.

Key words: reverse mining method, slope toe backfill, hanging wall ore, internal dumping
