      abstract     = {Before industrial revolution in the 19th century, mining
                      activity concentrated on near surface coal and ore deposits.
                      In the hard coal mining district of Aachen in close vicinity
                      of the river “Wurm”, near surface hard coal has been
                      mined in an area of about 19 km². Shallow mining dates back
                      to at least the 12th century in this district. The ancient
                      mines only reached depths of about 40 m below surface.
                      Nowadays, collapse features still occur in irregular
                      intervals above such shallow mining hollows and shafts,
                      being hazardous to infrastructure and human life. The hard
                      rock consisting of Carboniferous mudstones and sandstones of
                      low to medium strength is covered by clayey to sandy
                      Tertiary sediments, Quarternary sediments of the river Maas
                      and Loess/Loessloam on top. The thickness of the soil
                      overburden in most cases roughly varies between 15 and 25 m.
                      In recent years, intensive field investigations of collapse
                      features were performed. Based on these investigations, a
                      soilmechanical model of the collapse mechanisms in the soil
                      overburden was developed. This new model allows for the
                      prediction of the maximum width of collapse features
                      depending on the characteristics of the soil overburden;
                      these soil characteristics have been neglected in the design
                      of hazard zones in the hard coal mining district up to now.
                      New formulas for the estimation of hazard zones are
                      elaborated. The results of this thesis will be a basis for
                      an efficient future risk management in the mining district
                      of Aachen and later maybe also in other post mining
                      regions.},
