| Abstract: | The Leijiazhai Copper Mine ore body is thin to thick orebody with dip angles from 24° to 30°.The surrounding rock of roof and floor and the ore body are relatively stable.Based on the occurrence and stability characteristics of the ore and rock,the room and pillar method and chassis funnel open stope method are proposed.It's shown that the selected mining methods reduced the loss and dilution rate,which also improved the security of mining production.Moreover,the labor intensity is reduced and the economic efficiency is improved. |
