摘 要: “礦與非礦區(qū)分”是礦產(chǎn)地球物理勘探領(lǐng)域所面對的難題。由中南大學(xué)提出的偽隨機多頻相位法是一種較為有效的礦與非礦區(qū)分方法，該方法自提出以來先后在國內(nèi)10多個礦山的接替資源勘探中得到應(yīng)用。本文介紹了近年來針對這一方法開展的研究、取得的進展及成果。

Abstract:To distinguish ore and non-ore is a problem that the geophysical exploration of mineral resources is facing. The pseudo-random multi-frequency phase method put forward by Central South University can distinguish the ore and non-ore effectively. This method has been applied to the relay resources exploration in more than ten mines at home since it was first put forward. This article introduces the research on this method and the advancement of this method in recent years，at the same time introduces the gained fruits of this method with applied examples.
Key words: distinguishment of ore and non-ore; production mine; pseudo-random; multi-frequency phase method
