| Abstract: | The central sampling drilling is a new method which has the characteristics of efficient,accurate sampling and high percentage recovery of Core. This method is applied to the evolu-tion of the conglomerate gold deposits.The collected ore bed depth,grade,thickness and per-centage recovery of core satisfy need of geological work. Meanwhile,the normally geologiclog by using the returned substances can be finished. |
