矿产资源潜力评价省级预测成果汇总中的若干问题研究

Research on problems of prediction results summary for provincial evaluation of mineral resources potential

对省级矿产资源潜力评价预测成果汇总过程中存在的几个难点进行了总结与研究,包括预测模型建立、矿产地筛选、最小预测区筛选、二级归并区圈定及级别划分、海量图元属性对接、综合预测区圈定及级别划分、二级归并区与综合预测区资源量统计、综合预测区地质描述整理、勘查部署区顺序拟定等,提出了比较合理的解决方案。应用MapGIS二次开发技术编制了自动化处理软件,实现了预测成果的快速汇总。

The author gave research on summary of prediction results in mineral resource potential, including construction of predic- tion model, filter of orefield, filter of minimum prediction area, delineation and grade of merge area, docking between large number of pixels with attributes, delineation and grade of comprehensive prediction area, resource statistics in merge area, geological description of comprehensive prediction area, the order of exploration area. The author made some software tools, and these tools could quickly summarize the prediction results. The achievement gave a reference model to do similar works, and it was useful to the summary of pre- diction in other provinces.
