    摘要:

    覆盖区找矿难度不仅与覆盖层厚度有关,还与覆盖层物性、水文地质条件以及矿体特征关系密切。覆盖区找矿突破是一个系统过程,需要经历选区—圈靶—定位—验证评价4个阶段,存在勘查选区、地质信息探测和多学科有效融合难题。前人较少研究覆盖区找矿突破过程与勘查技术体系,笔者等基于“现有技术+结合实际创新”思路,总结提出了厚覆盖区找矿“循环渐近式勘查技术体系”,在实际应用中,能够提高找矿成功率,入选自然资源部《矿产资源节约和综合利用先进适用技术目录(2019年版)》。

    Abstract:

    The difficulty of prospecting in the overburden area is not only related to the thickness of the overburden,but also closely related to the physical properties, hydrogeological conditions and ore body characteristics.Prospecting breakthrough in covered area is a systematic process,which needs to go through four stages of selection,target setting,positioning,verification and evaluation.There are problems of exploration selection,geological information detection and multi-disciplinary effective fusion.There are few previous studies on the breakthrough process and exploration technology system in the covered area,In practical application,it can improve the success rate of prospecting, and is included in the catalogue of advanced and applicable technologies for mineral resources conservation and comprehensive utilization (2019 Edition) of the Ministry of naturalresources.Based on the idea of “existing technology + combined with practical innovation”,the author summarizes and puts forward the “circular and asymptotic exploration technology system” for prospecting in thick coverage area.
