Geotechnical solutions for linear transport infrastructure in mining areas

Design and construction of linear structures for transport like road or railway lines in areas with active or historical deep mining operations is always challenging due to various additional influential geotechnical data which needs to be considered. Surface subsidence and its negative impact on road geometry over time needs to be compensated by protection systems designed and implemented prior to time when real influence occurs. Linear or non-linear deformations are one of the most critical parameters to be overlooked at design stage. Also use of mining materials for construction of embankments as alternative to natural soils brings additional challenges and need for good identification of all geotechnical parameters of such material. As Silesia is region with one of the most concentrated deep coal mining activity in Europe problem of constructing safe and environmental friendly infrastructure is always critical. This paper discusses selected aspects of geotechnical practice implemented in the region for protection of transport infrastructure in such challenging geotechnical environment.
