1959年6月在内之岱矿区西部的第一个钻孔见矿后,虽然矿床规模仍在扩大,但从1960年1月起,已着手开发工作.两年以后,建成了一个月产2500吨原矿的采选企业.到1964年4月,它的生产规模扩大到3500吨/月.在这期间,通过坑道和钻孔逐步探明了矿区地质构造,将原来控制的预想矿量升级为确定矿量和推定矿量,并找到了一些新矿体.
After the first borehole in the western part of Dai mining area in June 1959 was discovered, although the deposit scale is still expanding, work has been started since January 1960. Two years later, a monthly production of 2500 Ton ore mining enterprises in April 1964, its production scale expanded to 3,500 tons / month during which, through the tunnels and boreholes and gradually identify the geological structure of the mine, the original control of the mine is expected to upgrade to Determine the amount of ore and the estimated amount of ore, and found some new ore body.
