Abstract: The adaptive of short-hole shrinkage mining method and mining method employing fill are contrastive analyzed.The necessity application of approach cut-and-fill stoping method and upward layer filling method in Liulou iron mine is analyzed in detail.The scheme of layer filling method,the technology of recycling pillar of layer filling mthod,some relative main problms and improvement measures are discussed so as to deal with the safety problem of approach cut-and-fill stoping method,eliminate the risks in the mined-out area,improve the recovery rate,reduce the dilution rate,make the mineral resources be recoveried effectively.

Key words: Approach cut-and-fill stoping, Upward layer filling method, Recovery of the mine pillar, Recovery rate, Dilution rate
