I would have thought chasing a band across a fault while problematic is not impossible to determine which direction the seam moved in.
surley test investigations of the stratigraphy above and below the seam could be easy pointers for displacement.

if the stratigraphy below the seam is present "in section" at the interface of the seam and the fault we know the seam has moved up.. and vice versa.

though i imagaine you YMRDV with this one as the degree of fault displacement may make investigating the stratigraphy above and below the seam rather problematic.

though the water flow and other logistical problems seem somewhat more of a challenge.

interesting post... up to standard

It is not that it can't be done, it is just that it is time consuming and expensive and when they were running longwall mining, moving the face through the fault or re-creating the face set up on the other side of the fault was not always simple.
