Protections and monitoring of European transportation routes in upper silesia mining area

The paper refers to the issues related to linear transport structures like roads and railway lines located on areas with the ground deformations caused by mining. Polish Upper Silesian agglomeration is a cluster of neighbouring cities forming a strip about 70 km wide with highly concentrated industrial and business activities. It is also a large transportation center - due to both the geographical location as well as the volume of transport. The construction and management of highway and railway lines in Upper Silesian urban agglomeration is a specific task. This is mainly because of the need to take into account strong ground deformations caused by intensive underground mining activities. Not only in still active coal mines, but also because of previous often forgotten mines, used over hundred years ago for extraction of silver, zinc, lead or salt. The paper shows the example of electronic monitoring system which was applied during construction of motorway A4 and A1 in Upper Silesia.
