| Abstract: | Complicated and hard-to-mine orebodies are essential in improving the utilization rate of geological resources. Take the transformation project of Fujia Mine from open-pit to underground mining for engineering back- ground,the paper in detail analyzed technical indexes of wing and wedge pillars in the 130 m stage. Based on production practices in Fujia Mine, the recovery technology of hard-to-mine orebodies is introduced. The recovery of such orebodies achieves satisfactory economic results and benefits the recovery of middle depth minor and residual hard-tomine orebodies in recovery design and construction for provision of new ideas and methods. |
