摘要
在地处四川西部高原山区的四川里伍铜矿外围上海底铜矿区处开展物探工作方法寻找铜矿。早期运用甚低频电磁法、高精度磁测、小极距激电中梯及充电法梯度观测工作,未达到找矿目的。这里根据工作场地的地形情况及地质情况,改变工作方法和技术手段,采用大功率直流激电中梯、激电测深及充电电位观测工作,获得了具有较好找矿意义的激电异常及充电电位异常,并在获得的异常处经验证已揭露出多个铜矿体,取得了较好的找矿效果。
This article introduce the method of Electrical prospecting to detect the copper ore at peripheral of Shanghaidi copper ore,in Liwu of western Sichuan plateau mountainous area.The early prospecting target has not been achieved by using low frequency electromagnetic,high precision magnetic survey,small IP intermediate gradient and charging gradient observation by other geography team.The author changes the work methods and technical means according to the work site terrain and geological conditions,by using large power DC IP intermediate gradient IP sounding,and charging potential observational workto obtain good prospecting significance of IP anomaly and the variation of potential abnormalities.Finally,very good prospecting effect and in the abnormal of the validation has been exposed a plurality of copper ore.
