Évaluation du risque d'instabilité en surface à l'aplomb d'une ancienne carrière souterraine. Principes d'une analyse par configurations types.

Abstract : INERIS developed a method for the assessment of surface subsidence hazard above old mine workings. This method is based on the definition of representative configurations characterised by the main causative factors in in-ducing instability. Each representative configuration is subjected to a systematic analysis in terms of potential movements that can occur from the mine to the surface. A surface subsidence hazard mapping is completed by extending the results of the analysis to any zone presenting a similar configuration. This method is applied for the assessment of old gypsum mine workings located in the East of France.
