Application of the terrestrial laser scanner technology to measure strata displacements in underground
excavations is becoming increasingly popular due to broad spectrum of measured data, its ease of use
and data quality it produces. Mine environment presents many challenging problems that limit application of
the laser scanner technology in unfavorable conditions including the explosion risk atmosphere, dust, humidity
and instability of mine excavations. This technology has been currently used to monitor the coal mine roadway
and pillar stability in the firstly developed room and pillar panel trial in the Czech part of Upper Silesian Coal
Basin (Czech Republic). The purpose is to monitor the long term coal pillar deformations that develop over time.
A comprehensive picture of the ongoing strata deformation has been obtained from the repetitive laser scanning
results. The strong roof strata subject to minimum deformation has provided the stable reference for scanning
purpose which is very important in evaluation process. The difference between each scan was then used to detect
changes in strata displacements.
