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

Abstract

© 2016 Sinopec Geophysical Research Institute.A low cost 2D reflection seismic survey was used to map the continuity of the main seams as well as the numerous faults at the Durdevik sub-bituminous coal deposit (BiH). A 24-channel seismic data acquisition system was available for this survey. The natural high reflectivity of the coal seams and a favourable geometry of seismic profiles enabled the identification and correlation of major faults across the area. Rugged terrain presented challenges to both data acquisition and processing. Stacks of acceptable quality were obtained only after the application of surface consistent statics and careful application of multi-channel filtering. A set of recorded 2D lines was interpreted in a 3D environment. Inferred structural elements disrupting the seam continuity were identified and were in agreement with available drilling results and mine workings. The result of this work was used to reduce mining hazards and also to help optimise mine planning.
