Mining Methods for Steep Medium-Thick Orebodies and Their Reform
The medium-deep mechanized caving open-stope delayed filling method is an underground mining technology suitable for steep medium-thick orebodies.With the development of mining technology and the in-creasing demand of productivity,the short-hole shrinkage stoping method can't no longer be adapted,and the medium-deep mechanized caving open-stope delayed filling method has been gradually applied to steep medium-thick orebodies and achieved good results.The three mining methods have been updated iteratively,and modern mainstream mining methods have been obtained,which meet current policy orientation and practical needs,and im-prove the mining efficiency of similar orebodies.
