Mine shafts in Nord-Pas-de-Calais coalfield (France) Risk assessment and treatment technique

Abstract : In France, coal concessions abandonment is fixed by legal procedures that lead the owner to achieve studies for the identification and the assessment of residual risks associated with underground mine workings. If necessary, treatment techniques must be defined in these studies in order to mitigate the associated risks for the population and future land planning. The multiplicity of mine shafts in coal mining areas have created many present-day problems. The main risks associated with mine shafts are the sudden collapse of their column and gas explosion, asphyxiation and/or intoxication. The Nord and Pas-de-Calais coalfield extends 100 km from East to West and 15 km from North to South. Coal exploitation induced the sinking of more than 600 shafts from 1716 to 1960 widespread over 41 concessions. The paper describes the work accomplished by INERIS and Charbonnages de France for mine shafts vicinity security.
