基于矿山勘查中的可控音频大地电磁测探发应用研究

Application of controlled source audio frequency magnetotelluric sounding method in mine exploration

现如今,我国的国民经济在不断的发展,社会在不断地进步,科技也在不断的发展,与常规物理勘探手段相比,可控源音频大地电磁法(CSAMT)具有勘探深度大、抗干扰能力强、工作效率高及分辨率高等特点,因此其被广泛应用于地下热水勘探、地质构造探测、隧道勘查,以及金属矿产勘查等,并取得了良好的勘查效果。通过对可控源音频大地测深法在不同领域应用现状的综述并举例说明,笔者认为可控源音频大地测深法作为一种地球物理勘探手段,拥有着其他物探手段无法比拟的优点,在现阶段具有不可替代性。

Nowadays, China＇s national economy is developing continuously, the society is constantly advancing, and the science and technology are developing continuously. Compared with the conventional physical exploration means, the controllable source audio magnetotelluric（CSAMT） has the characteristics of large exploration depth, strong anti-interference ability, high efficiency and high discrimination rate, so it is widely used in the field. Geothermal water exploration, geological structure detection, tunnel investigation, and metal mineral exploration have achieved good results. Through an overview of the application status of the controllable source audio sounding method in different fields and illustrating, the author thinks that the controllable source audio sounding method, as a geophysical exploration means, has the advantages unparalleled by other geophysical methods, and it is irreplaceable at the present stage.
