深部找矿基本问题及方法

中国经济社会发展与资源环境约束的矛盾日益突出，走向深部，向深部要资源，是矿产勘查的必然趋势。在论述深部找矿的重要性、必要性基础上，阐述了深部找矿的基本概念，总结了深部找矿的现状，梳理了深部找矿的难点，提出了"从成矿作用本质研究深部找矿问题，研究成矿地质体确定找矿方向，研究成矿构造和成矿结构面预测矿体位置，研究成矿作用特征标志提供预测依据，综合地质的、物探的、化探的、钻探的技术手段探测深部矿体，以间接找矿为主，直接找矿为辅"的深部找矿思路及方法，并对加强深部找矿工作提出了充分发挥理论指导找矿作用，创新、研发、推广适合中国特色的深部找矿技术，充分利用大数据等现代信息技术等建议。

Basic problems and methods of deep mineral exploration

The contradiction between the economic and social development and the restriction of resources and environment in China is becoming more and more prominent.It is an inevitable trend of mineral exploration to go deep and ask for resources in the depth.On the basis of discussing the importance and necessity of deep prospecting, this paper expounds the concept of deep prospecting, summarizes the present situation of deep prospecting, combs the difficulties of deep prospecting, and puts forward the thinking and method of deep prospecting:the problem of studying deep prospecting from the essence of mineralization, the study of metallogenic geological bodies to determine the prospecting direction, the study of metallogenic structure and metallogenic structure surface to predict the location of orebodies, the study of metallogenic characteristics to provide prediction basis, comprehensive geology, geophysical exploration, chemical exploration, drilling methods to detect deep orebodies.Indirect ore prospecting is the main method, while direct ore prospecting is the auxiliary method.Some suggestions are put forward to strengthen the deep prospecting work, such as giving full play to the role of theoretical guidance, innovating, developing and promoting the deep prospecting technology suitable for Chinese characteristics, and making full use of modern information technology such as big data.
