Summary In order to be able to survey caverns reliably, suitable installations and equipment must be kept available for testing and calibrating the systems used! For instance: test borehole fitted with multiple casing (4 1/2", 6 5/8", 9 5/8" and 13") for testing and calibrating the SUPER-CCL systems that are applied for determining the reference depth in accordance with the official guideline for the echometric surveying of caverns. |
|
For instance: mine shaft with access at depths of 750 m and 1050 m
for checking and calibrating the cables winches on the SOCON survey
vehicles!
