Ökologie der Fischbestände in Fließgewässern des Khentii-Gebirges (Mongolei): Bestandsaufbau, Dynamik und Gefährdung durch den Gold-Tagebau
… Ursachen für den Rückgang der Arten ist der Gold-Tagebau. Viele Goldvorkommen lagern in alluvialen Sedimenten der Fließgewässerauen und werden durch großflächigen Abbau und mechanische Auswaschungsprozesse gewonnen. Dies führt zu erheblichen Störungen im Schwebstoff- und Stoffhaushalt der …

Transportation system selection in open-pit mines (Truck-Shovel and IPCC systems) based on the technical, economic, environmental, safety, and social (TEcESaS) indexes
The production of raw materials through mining projects is nowadays very challenging, mainly due to the rapid progress in the industrial and technological fields. On the one hand, they have to fulfill industries' requirements in their demand for materials while making a profit based on the current …

Long-term open-pit planning by ant colony optimization
The problem of long-term planning of a hard rock open pit mine (discontinuous exploitation operation) is a large combinatorial problem which cannot be solved in a reasonable amount of time through mathematical programming models because of its large size. In this thesis, a new metaheuristic …

Bodenbewegungen infolge von Sümpfungsmaßnahmen für tiefe Tagebaue am Beispiel des Rheinischen Braunkohlenreviers
Lowering the groundwater table for the purpose of open-cast mining causes settlements over a wide area usually affecting the whole mining region and the surrounding areas. The lowering reduces the soil buoyancy in the affected layers thus causing settlements, while the reverse effect of the …
