{{OR/14/050}}&lt;br /&gt;
It was assumed that the borehole and well data proving the base of a unit was a correct interpretation at the correct depth and that this dataset has the highest confidence to fit the modelled surface. Visible inconsistencies were checked and removed as part of the modelling process.&lt;br /&gt;
&lt;br /&gt;
An assumed thickness, known to be a simplification, was used from a coal seam to a modelled horizon &lt;br /&gt;
([[OR/14/050 Model datasets #Mine plan data #Table 3|Table&amp;amp;nbsp;3]]) for the purpose of using the mining dataset as a projected constraint.&lt;br /&gt;
&lt;br /&gt;
Unit thicknesses are extremely variable within and between basins of the Midland Valley and so it is not possible to have a set of rules of unit thicknesses to be maintained. &lt;br /&gt;
