Combustion-type mining hazards in Pays de la Loire

Description

The notion of hazard is the probability that a given phenomenon will occur at a given site, during a reference period, reaching a qualifying or quantifiable intensity. The characterisation of a hazard is based on the intersection of the predicted intensity of the phenomenon with its probability of occurrence. The intensity of the phenomenon corresponds to the extent of the disorder, sequelae or nuisance that may result from the dreaded phenomenon. The notion of probability of occurrence reflects the sensitivity of a site to be affected by any of the phenomena analysed. Mining hazards are mainly collapses, subsidence, settlement, landslides, gas emissions, heating, flooding and water and soil pollution.
