摘　　要：地磁场数据处理涉及的内容颇多。实际工作中,应该针对地磁场异常特点和需要解决的地质问题,必须抓住数据处理的关键技术。本文通过对已知矿区地磁场数据的曲化平、向下延拓、局部场和背景场的分离等关键技术的应用,结果表明,经三种地磁场数据处理关键技术的应用,取得了良好的地质效果。Geomagnetic field data processing is involved in many aspects. In practical work, according to characteristics of abnormal geomagnetic field and geological issues to cope with,we must focus on key technology for data process- ing. This paper introduced application of key technologies in geomagnetic field data processing for a known ore dis- trict, such as reduction of curved surface into a horizontal plane,downward continuation, and separation of local field and background field. The application of these three key technologies has brought good geological result.
