3D MODEL OF LIMESTONE INCLUSIONS IN MARITSA IZTOK MINE BASED ON ELECTRICAL RESISTIVITY TOMOGRAPHY

Abstract

The 2D electrical resistivity tomography method (ERT) is a technique that can detect layers and geological features by exploiting resistivity contrasts between different layers using electrical current. This technique is useful for clearly determined resistivity boundaries, but limited where highly irregular or complex geological features such as inhomogeneous inclusions are present. In such a case 3D survey maybe required for inclusions type definition and also their size and location. The presented study demonstrates the efficiency of the ERT to map boundaries between distinct lithologies and detection of different inclusions on resistivity cross-sections
