RTB 11 Stratigraphic Panel — Sheet 28
Sheet 28 closes the 4-sheet RTB 11 profile; its upper boundary must join Sheet 27 without a duplicated or omitted depth interval. The thesis correlation places Seam A1 at about 29–37 m and Seam B2 at about 104–109 m in RTB 11, providing two separated anchors for testing track alignment and intervening stratigraphy.

Geological interpretation and evidential boundary
Sheet 28 closes the 4-sheet RTB 11 profile; its upper boundary must join Sheet 27 without a duplicated or omitted depth interval. The thesis correlation places Seam A1 at about 29–37 m and Seam B2 at about 104–109 m in RTB 11, providing two separated anchors for testing track alignment and intervening stratigraphy. Any scale reset, missing depth or track displacement at a sheet boundary can imitate a seam split or thickness change, so the page join is a geological quality-control step rather than a graphic detail. Taken with its neighbouring tranches, RTB 11 Sheet 28 is auditable correlation control—not independent evidence for depositional environment, coal quality or lateral persistence.
