Abstract:

Electrical resistivity imaging (ERI) was introduced to stone mineral exploration in order to resolve some actual problems such as ore body boundary determination and integrality distinguish. The ERI was used in a Heibinghua stone deposit exploration in Xinjiang. High resolution survey data was acquired by change survey line dispose and select appropriate equipment and then both 2D inversion and 3D tomography was done based on these dataset. The inversion results can be display, operate interactively realized by 3D visualize technology and then accomplish both interpret and evaluation for stone mineral. The result of ERI exploration indicate that this method can depict 3D shape of stone ore which have high resistivity, and it also indicate that ERI have stronger recognition capability for disadvantage factor such as mantle rock and cranny.

Key words: electrical resistivity imaging (ERI), stone mineral deposit, 3D inversion
