Underground Surveying

Accurate survey control is essential for underground operations. Survey Methods Total Station - Primary underground survey tool - Establishes control network - Marks drive centerlines Gyroscopic - Used for orientation in magnetically disturbed areas - Provides true north reference Geological Applications - Accurately locate mapping data - Position drill hole collars - Measure structure orientations - Create 3D interpretations Reference Points - Survey marks spads in backs - Reference lines on walls - Known elevation datums
