摘要
在总结前人对龙门店银铅矿勘查成果的基础上,选用CSAMT法进行深部矿致异常追索,在综合考虑近场效应及人工场源电磁信号强度的问题上,对CSAMT方法的收发距及频率设置进行了优选试验。应用结果表明,CSAMT法对深部银铅矿有较好地响应,与后期钻孔资料的吻合度较高,表明CSAMT法在本区寻找银铅矿是有效的。
In this paper,based on the previous research on the results of Longnan silver and lead exploration,the CSAMT method is used to exploring the deep mine.The optimal tests on the distance of receiving and transmitting and setting frequencies considering the problem combined with the near field effect field and signal strength of electromagnetic field are carried out.The application results show that it is an effective method of CSAMT for exploring deep silver-lead ore,verified by later drilling data.
