中文摘要：

独山半坡锑矿石与围岩物性差异并不特别显著、矿体埋深较深,常规的物探方法无法满足目前的勘探要求.可控源音频大地电磁法（CSAMT）具有勘探深度范围大、分辨率高、地形影响和高阻层的屏蔽作用小,立体观测等特征,在深部找矿中发挥着重大的作用.本文首先概述了CSAMT基本原理和工作方法,在全面掌握了地质资料、物性参数的基础上,对独山半坡锑矿外围开展了CSAMT法勘探,通过应用Occam算法对CSAMT实测数据进行反演,成功地圈定了电阻率异常区域,有效地指导钻孔设计.物探异常钻探见矿,验证了CSAMT方法在深部找矿工作中的有效性,可为寻找同类深部锑矿提供指导和借鉴意义.

英文摘要：

Dushan Banpo antimony ore and rock physical difference is not particularly significant,ore bodies buried deep,conventional geophysical method unable to meet the requirements of the current exploration. Controlled source audio magnetotelluric method（ CSAMT） has great exploration depth,high resolution,influence of topography and high resistivity layer shielding effect,stereoscopic observation characteristics. For deep mine plays an important role.This paper begins with an overview of the CSAMT basic principle and working methods,in a comprehensive grasp of the geological data,based on the physical parameters of the,of Banpo antimony peripheral carried out CSAMT exploration,through the application of Occam algorithm of CSAMT data inversion, successfully delineated the resistivity anomaly area,effectively guiding drilling design. The drilling of geophysical anomaly see mine of CSAMT method is verified for ore in the deep,to provide guidance and reference significance to find similar deep antimony.
