The paper presents the results of experimental and methodological seismic and electrical exploration along the profile crossing the productive formation of coal seams in the Gorlovsky anthracite basin (Doroginskoye deposit, Shadrinsky block). The obtained CDP time cross sections indicate the possibility of displaying some elements of the folded structure of thick anthracite seams in the wave field at depths up to 300-350 m. Seismic tomography with the use of first arrivals of longitudinal waves allows scientists to reconstruct in detail the velocity structure of the near-surface part of the section to depths of 120-150 m and to identify low-velocity local objects corresponding to the upper edges of the thickest coal members in the upper part of Permian deposits.

Keywords: Gorlovsky anthracite basin, CDP time cross sections, seismic tomography profile, velocity anomalies.
