地质资料二次开发在矿山找矿中的作用

APPLICATION OF SECONDARY DEVELOPMENT OF GEOLOGICAL MATERIALS TO PROSPECTING OF MINES

地质资料二次开发就是对已有地质资料再次进行系统而全面的分析。应用于矿山二轮找矿时，大致包括如下４ 方面的工作，即１） 原始地质资料的“去伪存真，去粗取精”处理；２） 运用新理论，并且做到理论联系实际；３） 正确理解不同研究者的观点和认识；４） 不断提出新的地质问题。琅琊山铜矿、十里铺银矿、锡铁山铅锌矿地质资料的二次开发研究结果表明，这一方法对于开展大比例尺找矿预测。

The secondary development of geological materials is a special kind of work in which the original ones are systematically analysed again. In the secondary prospecting of mines, the secondary development of geological materials includes four steps: (1) to extract the real and useful information from the original geological materials, (2) to use new theories and integrate them with practice so as to solve the unsettled problems, (3) to understand correctly diverse ideas and thoughts from different researchers, and (4) to be incessantly able to raise new geological problems. The success of secondary development of geological materials in the Langyashan Copper mine, Shilipo silver mine and Xitieshan Pb-Zn mine shows that it is an effective and very useful method for the large-scale prognosis and prospecting in mines.
