Collapse/subsidence : role and influence of overburden in Lorraine iron mines case

Abstract : This paper presents several large-scale numerical modellings of valley and tray situations with the presence or not of vertical fractures. Through these modellings, we firstly attempt to evaluate an influence zone, in terms of stress variations induced by the creation of the valley. Next we study more particularly the behaviour of a stiff overburden, according to situations, with the aim to estimate if a valley and/or the presence of subvertical fractures influence the overburden massivity.
