The method has the advantage that the ore body can be easily delineated from the carbonaceous layer.

Description

technical field [0001] The present application relates to the technical field of ore body exploration, in particular to a method and system for ore body exploration using time-domain induced polarization method. Background technique [0002] Nowadays, in the ore body exploration work, the direct current method can be used for exploration, and the direct current method is also the most commonly used exploration technology at present, and the time-domain induced polarization method is an important part of this exploration technology. Therefore, the research on the spectral IP effect changing with frequency or time has always been a hot spot in the development of IP method, and many achievements have been made in terms of equivalent models, working methods, physical experiments, and instrument development. Spectral parameters are used as auxiliary explanations. The methods have also been gradually applied, but they are mainly applied to ground frequency domain methods. With th...

Problems solved by technology

[0004] Regarding the above-mentioned related technologies, the inventor believes that there are the following defects: when carrying out exploration and ore prospecting operations in a relatively complex geological environment, it is difficult to analyze and interpret the time-spectrum effect in the above-mentioned technologies due to the relatively single observation parameters. It is difficult for the model to interpret and analyze the exploration results in a relatively complex geological environment, which makes it difficult to distinguish the ore bodies in the carbonaceous layer in the formation, which affects the smooth progress of ore prospecting operations
