Because the inclination of the thick ore body is small,and there is a weak interlayer in the middle,the mining of such ore body can not rely on the weight of migration,so the roof management is difficult and the mining cost is high,which is a technical problem.This paper analyzes the advantages and disadvantages and application conditions of filling mining method,collapse method and house column method,expounds the selection basis of mining method and introduces the latest research progress of filling mining method.This work can provide guidance for the selection of mining methods for slow,medium and thick deposits.
