Modelling of a coal seam of the deposit Đurđevik (BiH) by means of 2D reflection seismic imaging

Coal: exploration, reserves, and utilization

“…The registered physical parameters are usually indirectly dependent on the petrological and petrophysical characteristics of the rocks. Geophysical [27,28] borehole logging devices are classified as (i) passive, where the physical properties of the formation in the borehole are registered without exciting the formation (self-potential, pressure, temperature, natural radioactivity) and (ii) active, where the formation is excited (electric current, electromagnetic waves, acoustic waves, radioactive radiation) and the effects created as a consequence of excitation are measured. The response of geophysical well logging devices depends on the properties of the formation (lithological composition, rock assembly, geometry of pore space, type of fluid in the rock, etc.…”

Identification and geovisualization of landscape transformation of surface mine areas in the Đurđevik coal basin (Bosnia and Herzegovina)

“…The seam most often lies over lumpy marly-sandy clays and gravels, while the roof is predominantly made up of a series of Lower and Middle Miocene marls and marly limestones (up to 240-300 m thick). Uppermost Pliocene and Quaternary series have a thickness up to 60 m (Arsenović et al, 2016). In the Đurđevik coal basin, a coal seam of different depths has been developed.…”
