Abstract
The options of electrical tomography in studying complex-structure geological profiles in coal deposits are examined using mathematical modeling of electrical fields in nonuniform media. The modeling results show regular patterns of electrical fields distribution, which are used to interpret in situ data to build background models aimed at defining shape, size, occurrence conditions and physical properties of mineral deposits in weak-differentiated media. The study is illustrated by experimental research conducted on a lignite coal field.
