靶区优选是矿产勘查中的一个关键环节,它既是矿产资源预测成果的直接体现形式,同时又是联系矿产资源预测与勘查工作部署的桥梁.然而,由于人们认识上的不完备性和缺乏相应的技术手段支撑,使得靶区优选常被忽视或简化.探讨了靶区优选的地质基础原则,建立了靶区优选的技术流程,研发了基于GIS支持下靶区优选计算机辅助决策模块,并以云南省个旧地区与岩浆活动有关的锡铜多金属矿靶区为例进行了示范研究.结果表明靶区优选技术及相应的软件能够客观地反映不同靶区的特征,提高靶区优选的智能化程度和工作效率.
Target area optimization is a key link in mineral exploration, which is not only a direct manifestation of mineral resources prediction results, but also a link between mineral resource prediction and exploration deployment.However, due to incomplete understanding and lack of corresponding knowledge , The optimization of target area is often neglected or simplified.This paper discusses the preferred geological principle of target area, establishes the preferred technical process of target area, develops a computer-aided decision-making module based on GIS, The case study of the tin-copper polymetallic ore target related to magmatism in Gejiu area, Yunnan province, as an example, shows that the target area preferred technology and the corresponding software can objectively reflect the characteristics of different target areas and enhance the intelligent optimization of target areas Degree and efficiency.
