For this project we chose a Carl Zeiss Ni2 level made in the 1960s.

Quarry Monitoring

In Slovenia, a team monitored slope stability in an open-pit quarry using a classic, optical precise level and Invar rod.  Editor’s note: Cost-benefit analysis dictates that, for open-pit mines and quarries, steep slopes allow for the most efficient extraction of resources but at an increased risk of slope failures. This adapted paper outlines an example...

Feature: Details of Deformation Monitoring

When evaluating automated versus conventional deformation monitoring for a major rail project in Slovenia, automated clearly wins.Editor’s Note: PSM has examined several automated deformation monitoring case studies; due to technological advances, automated monitoring has gone mainstream. The following adaptation of an academic paper provides a direct analysis of project operational considerations and cost comparisons. Intuitively,...
