摘要
微动法的场源是天然源,属于被动源法。可控源音频大地电磁法(CSAMT)是人工源,属于主动源法。被动源法勘探成本低、仪器设备轻便、具有绿色勘探特点。主动源法勘探成本高、仪器设备复杂笨重、工作效率低,但方法技术研究程度高,能发挥勘探技术人员主观能动性,可提升勘探效果。本文介绍两种场源联合勘探应用实例,评述其应用效果。
The microtremor method whose field source is a natural source belongs to a passive source method.Controlled source audio magnetotelluric method(CSAMT)is an artificial source and an active source method.Passive source exploration is low in cost,light in equipment,and is environmentally friendly,while active source is high in cost,complicated and cumbersome in equipment and low in work efficiency,but its high degree of research can give a play to the subjective initiative of exploration technicians and improve the exploration effect.This paper gives an example on how the two methods are applied in exploration and discusses the result.
