Utilization of ground subsidence caused by underground mining to produce a map of possible land-use areas for urban planning purposes

The presented work deals with a new type of map titled-a map of a possible area use for planned built-up area purposes in areas affected by underground mining-related subsidence. Generally, accepted theory of a subsidence basin must be applied to such areas, and in order to produce the map, ground subsidence isolines, land-use plan, and slope deformation distribution were considered. The map can be used by land-use planners, future developers, investors, engineering geologists, etc. to inform future development of such land. It is clear that land-use planners may not have sufficient knowledge to decide whether the ground subsidence value is acceptable or not for a particular development purpose. At the same time, it shows that the existence of slope deformations also influences the siting of new buildings in undermined areas and therefore these were included in the map compilation process. The outcome is three area categories where mining subsidence impacts surface development, namely-low influence on the planned development, economically acceptable influence on the planned development, and extreme influence with development prohibited. The research was carried out in the Darkov Region in the northeast of the Czech Republic, where black coal is mined and extensive mining impact on the surface identified. The map produced in this study will help the controlled development of the region by means of appropriate land-use planning.
