| Abstract: |
| The feasibility of which short-hole shrinkage method is used for mining of low-grade and submarginal ores in Huanren Mine is demonstrated in this paper.If this mining plan is put into practice,the mine life can be expanded for 1.6 years and the mineral resources in our country can be utilized sufficiently,including recovering 286kt of iron concentrate(equal to 185.8kt of metallic iron),6332t of copper concentrate(equal to 475t of metallic copper). |
