Use of multi-criteria decision-aids for risk zoning and management of large area subjected to mining-induced hazards

The end of iron-mining operations in France''s Lorraine region has raised the problem of post-mining management. Collapses and subsidence have recently occurred in this region, which focused on the necessity to develop a specific methodology for risk zoning. The proposed methodology is based on the multi-criteria decision-aid approach called ‘ELECTRE TRI’, with aim to assign zones at risk into predefined classes. It allows experts opinions, qualitative and quantitative criteria and uncertainties to be taken into account. [Copyright &y& Elsevier]
