The results of experimental and methodological seismic and electrical exploration of near-field time-domain electromagnetic sounding (NFTDES) along the profile crossing the productive formation of сoal seams in the Gorlovsky anthracite basin (Doroginskoye deposit, Shadrinsky block) are presented. The possibility of studying coal-bearing series at depths up to 300-350 m is noted. The obtained CDP time cross sections indicate the possibility of displaying some elements of the structure of thick anthracite seams in the wave field, that allowing for reconstruction of their folded features. Using the first arrivals of longitudinal waves (at distances up to 800 m), seismic tomography 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 weathering crust and in the upper part of Permian deposits. The resolution of velocity profile decreases at a given length of the traveltime graph with a further increase in depth to 300 m.
SUMMARYEngineering-seismic studies of the shallow subsurface in the Teberda River valley (Karachay-Cherkess Republic) were carried out with the aim to rectify spatial boundaries of ground-water deposits in the river paleocut, being a promising target for water by the results of previous prospecting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
