Evolution of water quality in the abandoned iron mines of Lorraine: towards a semi-distributed modelling approach

Abstract: In Lorraine, flooding of the iron mines leads to a degradation of groundwater quality. Based on a global approach, a numerical simulator has been built that can reproduce and predict the evolution of water quality at the overflow point of the mining basin. In order to specify the spatial distribution of these pollutant concentrations, a new model has been developed. The basin is represented as a network of homogeneous reservoirs. Although encouraging, the results show the need to specify the spatial organisati… Show more

“…Closed reactor tests were carried out [7]. They consisted in bringing rock (5 mm < ∅ < 10 mm) into contact with Dogger water (water supplying the mine) (Table 1) so as to characterise water-rock chemical equilibrium.…”

“…Afin d'étudier les équilibres chimiques qui s'établissent entre l'eau et la roche lors de l'ennoyage des mines de fer lorraines, des essais en réacteur fermé ont été réalisés [7]. Environ 0,59 kg de roche broyée (diamètre des grains inférieur à 5 mm) et 0,28 kg d'eau du Dogger (Tableau 1), qui alimente le réservoir minier, ont été introduits dans des flacons d'un demi-litre en polypropylène.…”

“…Unlike the neighbouring Lorraine Iron Basin where the impact of mine flooding on water quality is studied for water supply concerns (e.g. Collon et al, 2005Collon et al, , 2006Hamm et al, 2008), the great depth (up to 1.5 km) and the favourable local geothermal gradient (around 3.5°C/100 m) in the Lorraine Coal Basin make it a potential resource of low-temperature geothermal energy. Preliminary investigations were carried out by Hamm and Bazargan Sabet (2010), who identified the area of the Merlebach mine, centred around the Vouters 2 mineshaft (Fig.…”

“…Étant donné la complexité de la structure du système hydrogéologique, les modélisations sur ce sujet ont été, dans un premier temps, nécessairement globales (ex. : COLLON et al, 2005). Nous essayons ici de modéliser dans l'espace les écoulements, perturbés notamment par la présence des anciennes galeries de mine.…”
