Abstract:

According to the characteristics of big coefficient of variation of orebody thickness in Xinhui gold mine, combine with the actual geological occurrence conditions of ore block,we choose level stratification sub-sequent filling mining method and stope mining,and exploit ore block.We obtain good results,and it has value of increase promotion.

Key words: Fill mining method, Stope mining, Mutation of orebody thickness, Xinhui gold mine, Shandong Province
