摘要
在分析矿床地质特征基础上,根据岩矿石物性特征,在矿区开展激电扫面和高精度磁测工作。通过磁测工作寻找对成矿有利的隐伏岩体,激电扫面圈定出了矿区内控制矿体的构造破碎带,综合激电异常和磁异常特征,通过钻孔验证,取得了良好的找矿效果。
The terrestrial laser scanning and high-precision magnetic survey is carried out in the mining area according to the petrological and mineralogical characteristics on the basic of analysis on the geologic features of deposit.The concealed rock body,which is beneficial to mineralization,is sought by high-precision magnetic survey;the structure fracture zone that controlling ore bodies inside the mining area is determined by terrestrial laser scanning,the integrated induced polarization anomaly and magnetic anomaly characteristics is verified by drilling,which gets the good mineral exploartion effect.
