金矿地球物理勘查方法综述

Review of geophysical prospecting methods for gold ore

当前,金矿开采过程已经由地球表层逐渐向深部发展,由老矿区向新矿区过渡。传统地质矿产勘察方式限制条件较多,已经无法满足当前金矿开采要求。地理物理勘查技术应用范围不断扩大,在金属矿勘探中发挥了重要作用。本文对地球物理勘查技术在当前金矿勘查中的应用进行了分析和研究,总结了重力、电法、磁法、地震以及放射性物探技术在当前金矿勘查中的应用方法,同时以实例分析法验证了不同勘查技术在不同类型金属矿床中的应用要求,展望了地球物理勘查技术在今后金矿勘查中的应用前景。

Nowadays, the gold mining has gradually developed from the earth surface to the deep, and transitioned from the old mine to the new. With many restrictions, traditional geological and mineral prospecting methods cannot meet current gold mining requirements. The application of geophysical exploration technology has been continuously expanded, which has played an important role in metal ore prospecting. This paper has analyzed and studied the application of geophysical prospecting technology of the current gold deposit exploration, and summarized the application methods of gravity, electrical, magnetic, seismic, and radioactive geophysical prospecting techniques in the current gold mine exploration. Through case study, the application requirements of different exploration technologies in different types of metal deposits have been verified. Also, the application prospects of geophysical exploration technologies for future gold exploration have been discussed.
