Abstract: Copper-silver deposits are widespread.The current exploration requires that besides the main minerals, targeted exploration should be carried out for minerals with medium scale or above.At the same time, the standard requirements of the exploration engineering spacing between copper and silver is big, it's difficult to share a common exploration strike direction spacing for them.In order to solve this problem, this paper puts forward the theoretical method of “comprehensive exploration system”, which lets the copper-silver deposit share a set of exploration system, and only carries out trend encryption on silver minerals with tight exploration requirements.The significance lies in the full utilization of the same set of exploration lines and the coordinated application of the exploration standard requirements of each ore engineering spacing.Taking the Jinjiwo copper-silver deposit in Jiangxi province as an example, this paper shows that it is more reasonable and economically to silver exploration strike direction engineering spacing of 100 m and tendency direction engineering spacing of 100 m, and only increase 1 times engineering on tendency direction for silver ore in the Jinjiwo deposit.The exploration precision can meet the requirements while making full use of existing engineering and reducing exploration investment.This method can be applied to copper-silver deposit symbiosis in China, especially Ⅱ exploration type of ore deposits to achieve a more reasonable exploration to decorate.The connotation of ideas can also be extended to all mineral deposit.The use of exploration standard should be fully aware of the uniqueness of each deposit.
