Developments in volume and ground deformation monitoring

Two techniques are presented. In the first one a laser optical range finder is developed for measuring and setting our distances to undefined inaccessible objects. The use of the developed prototype in quarry, stope and open pit surveying is investigated. In the second technique a differential subsi...

Description
Summary:Two techniques are presented. In the first one a laser optical range finder is developed for measuring and setting our distances to undefined inaccessible objects. The use of the developed prototype in quarry, stope and open pit surveying is investigated. In the second technique a differential subsidence meter is developed for high precision measurement of the ground deformation due to mining. The developed prototype is capable of measuring the progressing ground tilt with an accuracy of a fraction of a second.
