Structure contour and distribution — Seam B2
The B2 structure-contour and surface pair is built from three boreholes, an interpreted thickness of about 4–5 m, and a source-reported attitude of N291°E/24°. Contours summarize the interpolated roof or floor elevation; they are not additional measurements between boreholes.
SOURCE-LED TECHNICAL READING
Geological interpretation and evidential boundary
The B2 structure-contour and surface pair is built from three boreholes, an interpreted thickness of about 4–5 m, and a source-reported attitude of N291°E/24°. Contours summarize the interpolated roof or floor elevation; they are not additional measurements between boreholes. The surface is most defensible inside the control polygon and progressively less certain toward model edges, where algorithm choice can dominate apparent curvature and thickness. Quality control should test the surface against every seam intersection, topographic clearance, stratigraphic order and leave-one-well-out alternatives. The figure demonstrates a coherent working geometry, not a reserve estimate or proof that dip and thickness remain constant outside the drilled area.
