Grisou — Wikipédia
Le grisou est l'une des formes de carbone fossileIl se distingue du gaz naturel par sa composition et sa formation Il est composé à plus de 90 % de méthane [1]Ce gaz invisible et inodore se dégage des couches de charbon et des terrains encaissants lors de leur exploitation [2], [3]Comme le radon, à très faible dose, il fait partie de l'atmosphère normale des minesUne rupture de barrage se produit lorsque la structure cède du fait d'événements naturels (séisme, mouvement de terrain, crue, etc) ou de défaillances humaines (mauvaise conception, négligence, sabotage, etc)Cette rupture a pour conséquence le déversement non contrôlé de l'eau ou de la boue contenu par le barrageCe type de catastrophe reste peu fréquent maisRupture de barrage — Wikipédia
