Abstract: Bailingshan iron mine in Shanshan county,Xinjiang is gently inclined thin ore body and can be recovered with the shallow hole room-pillar mining method.When the large and thick ore-body appears in local places,it is difficult to recover the top ore-body.In order to solve contradiction between the scraping and stoping,this paper improved mining method,by intergrading room-pillar method and shallow hole shrinkage,which successfully resolve series of problems such as local ore bodies' stopping,stope safety,pedestrian,ventilation and transport so on.The loss rate and the dilution rate reach 11.58% and 5.1% respectively.It provides experiences for the similar ore body stoping.

Key words: Room-pillar, Shallow hole shrinkage, Comprehensive deformation scheme
