Modelling of coal seams in the Nottingham-Melton area : methodology and specifications

By T. Huw Sheppard


3D models of coal seams in the Langsettian and Duckmantian of the Nottingham-Melton district were gerenerated from 1) borehole, 2) mining and 3) seismic datasets. The surfaces were produced by Kriging interpolation of data points using Golden Software’s SURFER package. Surfaces derived from borehole data were a) interpolated, taking account of fault lines; b) recalculated to avoid intersections, c) blanked to remove intersections with the Variscan unconformity, d) blanked to remove intersections with fault lines. Surfaces derived from seismic data were regenerated from previously interpolated dataset, whilst surfaces derived from mining data were treated in the same manner as the borehole dataset. Composite models, taking into account borehole, seismic and mining data, were generated for three of the six coals examined. All models were exported to ArcScene and GoCad for visualisation and GLOS storage, and to xyz ASCII for storage in the GSF
