Core photographs — Seam B1
Seam B1 is correlated through RTB 11, RTS 74 and RTS 06 as a comparatively thick, approximately 9–14 m coal body. Clay partings of roughly 0.5–2.5 cm are recorded within the seam and must be carried into any clean-coal thickness or quality calculation.

Geological interpretation and evidential boundary
Seam B1 is correlated through RTB 11, RTS 74 and RTS 06 as a comparatively thick, approximately 9–14 m coal body. Clay partings of roughly 0.5–2.5 cm are recorded within the seam and must be carried into any clean-coal thickness or quality calculation. In the thesis evidence chain, the photograph records recovered material and superposition but does not directly demonstrate between-well continuity. Core-scale banding and partings may be described visually; coal rank, peat affinity and quality cannot be inferred without the laboratory dataset. Correlation through three boreholes is strongest where the photographed contacts coincide with the same gamma and density markers in depth; recovery loss, fragmentation and depth mismatch must be ruled out before a thickness difference is treated as geological. Where this panel also occurs in the internship report, the duplication is treated as traceable reuse rather than replication.
