Abstract
The necessity to protect cultural heritage is indisputable. The paper present two important metrological problems connected with the assessment of the condition and behavior of two monumental structures located in mining-influenced area in Upper Silesia region. The first problem has been effectively solved through using laser tilt and vibration sensors designed at the Central Mining Institute's Laser laboratory, while the other is to be investigated by using acoustical holography to detect the structure of the castle's foundation and its surroundings in the ground. The paper present the experimental results obtained with the use of both methods. An analysis of the tilt sensor at the castle show special effects of its behavior which are to be related to other factors outside mining. These factors need further detailed investigation. The method of acoustical holography has been experimentally verified in detecting the model structure of underground workings.
