What is a wall station

It is the terminology used by Surveyors working in the underground mining environment that refers to a survey reference point created by a stem and prism placed in an alignment tube or hole.

The wall station is a reference point that has known E, N, RL coordinate values.
Two or more wall stations (reference point) are used in a series of measurements to compute a coordinated resection position for the instrument.
When the prism and stem are removed from the wall station the reference point is a position floating out in space.
