Cores and samples contain abundant geological information and play a very important role in mine geological prospecting .On the basis of previous work ,the author summarized the working methods for the secondary development and utilization of physical geological data and solved the geological problems in the mine ,summed it up into a solid field geological work ,discovering geological problems ,re-analyzing the results and original data ,and determining the ideas or methods of work ;re-useing of physical data ,extraction of geo-information ;re-understanding of geological issues and achieving results .Taking Yankou Rock salt mine as an example ,through the reuse of physical geological data ,the cause of the deposit was determined , and the direction for further exploration was determined .This example shows that the scientific development of the existing geological cores and samples is an effective way to study deposit genesis and solve the prospecting problems with the continuous geological work .%实物地质资料蕴含着丰富的地学信息,在矿山地质找矿工作中发挥着非常重要的作用.在前人工作的基础上,本文总结了实物地质资料二次开发利用解决矿山地质问题的工作方法,将其归纳为:进行扎实的野外地质工作,发现地质问题;将成果及原始资料进行重新分析,确定工作思路或工作方法;对实物资料进行重新利用,提取地学信息;重新认识地质问题,取得成果.以宁夏硝口岩盐矿为例,通过重新利用实物地质资料,确定了矿床成因,进而确定了下一步的找矿方向.该实例表明,随着地质工作的不断深入,科学开发已有的实物地质资料是研究矿床成因、解决找矿方向的有效途径.
