Three-dimensional model of all principal coal seams
The stacked three-dimensional view assembles all principal seam surfaces into one geometric hypothesis. Correct superposition and broadly coherent dip are encouraging, but they are necessary rather than sufficient tests: independently interpolated surfaces can look orderly while carrying the same biased picks.

Geological interpretation and evidential boundary
The stacked three-dimensional view assembles all principal seam surfaces into one geometric hypothesis. Correct superposition and broadly coherent dip are encouraging, but they are necessary rather than sufficient tests: independently interpolated surfaces can look orderly while carrying the same biased picks. The model should be interrogated for crossing seams, unrealistic thickness gradients, edge effects and sensitivity to leaving out individual boreholes. Within the collar network it is a useful synthesis; beyond that network it becomes an extrapolation whose confidence must decay explicitly.
